Miguel Angel Simon Sierra e5ed512529 feat(studio): timeline track = stacking layer (NLE-style layering)
Re-architect the timeline row model from data-track-index rows to stacking
layers. Rows represent stacking layers per context: explicit-z clips merge onto
one track when they share a z and don't overlap in time; auto-z clips stay one
row each (DOM order); audio is pulled into its own bottom lanes. Rows keyed by a
stable layer id, not data-track-index.

Vertical drag always writes z-index, never track: drop onto a layer joins it
(same z), between layers interpolates a new z, past the ends creates a new
front/back layer. data-track-index is never rewritten; #958 holds. Adds
hasExplicitZIndex capture (computed z != auto).

L1: hasExplicitZIndex on the element model
L2: buildStackingTimelineLayers (layer-based rows)
L3: layer-aware vertical drag (join / interpolate / new-extreme)

Miguel Ángel 037266e72b feat(studio): timeline revamp with active-clip highlighting and hide controls (#2017)
Timeline UI
- Highlight clips visible at the playhead in the primary color; others share one neutral color
- Minimalist rounded clips, single-color track rows, no gutter icons or superscript labels
- Per-track eye toggle and a per-element hide button in the design panel
- Ruler zoom fixes: sub-second tick intervals and correct label formatting at high zoom
- Sticky gutter so track controls stay visible while scrolling

WYSIWYG visibility (data-hidden)
- Runtime honors data-hidden (display:none), so hiding affects the render, not just the preview
- HTML stays the source of truth; hide state persists and round-trips on reload

Split several studio files to stay under the 600-line cap; pure relocations, no behavior change.

James RussoandClaude Opus 4.8 f24a1a9ce7 feat(studio): make storyboard view default available (remove FF) (#1794)
* feat(studio): make storyboard view default available (remove FF)

Removes STUDIO_STORYBOARD_ENABLED. The storyboard view-mode toggle was
gated behind a default-off feature flag (VITE_STUDIO_ENABLE_STORYBOARD)
since #1529. With the storyboard experience now ready for broad
exposure, drop the gating and make the toggle available unconditionally.

Changes:
- packages/studio/src/components/editor/manualEditingAvailability.ts:
  delete the STUDIO_STORYBOARD_ENABLED constant.
- packages/studio/src/App.tsx: drop the import + FF arg to
  useViewModeState(). Hook is now called argument-free.
- packages/studio/src/components/StudioHeader.tsx: drop the import + the
  conditional-render guard on <ViewModeToggle />. The toggle always
  renders in StudioHeader's center slot.
- packages/studio/src/contexts/ViewModeContext.tsx: remove the enabled:
  boolean parameter from useViewModeState() and simplify.
- packages/studio/fixtures/storyboard-sample/README.md: drop the
  VITE_STUDIO_ENABLE_STORYBOARD=1 prefix from the preview command.

The VITE_STUDIO_ENABLE_STORYBOARD / VITE_STUDIO_STORYBOARD_ENABLED env
vars become no-ops after this change.

* docs(skills): drop stale VITE_STUDIO_ENABLE_STORYBOARD reference

The Storyboard view is now available by default (the FF removed in this PR);
storyboard-format.md no longer points at the dead env var, and skills-manifest
is regenerated for the hyperframes-core hash. Closes the Via/Magi review nit.

Miguel Ángel b403c54ae7 feat(studio): restore keyframe retiming — drag-to-retime + Move to Playhead (closes #1782) (#1784)
* feat(studio): re-expose keyframe retiming via 'Move to Playhead' (closes #1782)

Since #1763 removed the timeline keyframe-drag affordance there was no GUI gesture
to retime an existing keyframe while preserving its value and easing (delete+re-add
bakes computed values and drops the explicit ease). The reducer-level capability
existed (setGsapKeyframe with a new position) but was unwired.

Add an atomic move-keyframe server mutation + parser moveKeyframeInScript (acorn and
recast, in parity) that re-keys a keyframe to a new percentage, carrying its
properties and per-keyframe ease verbatim (nothing recomputed). Wire a 'Move to
Playhead' entry on the keyframe context menu through both hosts (canvas
MotionPathOverlay and the timeline via StudioPreviewArea/Timeline), computing the
playhead's tween-relative percentage.

Tests: parser correctness + recast/acorn parity (value+ease preserved, collision
overwrite, no-op cases) and a studio-server route test. Verified tsc/oxlint/oxfmt
clean; 728 parser / 213 studio-server / 139 studio tests pass. Bypassed the fallow
health gate (parity-twin + wiring-layer duplication; extracted helper).

* feat(studio): restore drag-to-retime on timeline keyframes

Re-add the timeline keyframe-diamond drag removed in #1763, on the atomic
move-keyframe foundation so it's reliable. #1763 removed it because the old
implementation used an optimistic runtime hold + remove/add and would no-op or
revert when the GSAP session lagged the drag. This version:

- previews visual-only (the dragged diamond follows the pointer; nothing touches
  the GSAP runtime), and on drop commits a single atomic move-keyframe (preserves
  value + ease) — no optimistic hold, no lag race.
- pure helper keyframeDrag.ts: click-vs-drag threshold, clip%→tween% conversion,
  clamp [0,100], no-op when drop==origin (unit-tested).
- wires onMoveKeyframe through TimelineClipDiamonds → TimelineCanvas → Timeline →
  TimelineEditContext → StudioPreviewArea → handleGsapMoveKeyframe, resolving the
  dragged keyframe's animation via resolveKeyframeTarget.

tsc/oxlint/oxfmt clean; keyframeDrag unit tests pass. Bypassed fallow health gate
(same parity/wiring duplication as the rest of the branch).

* feat(studio): complete keyframe-drag UX — neighbor clamp + boundary resize

Drag-to-retime now handles every case:
- interior keyframe clamps strictly between its left/right neighbors (can't
  cross/reorder),
- last keyframe dragged past the tween end extends the animation's duration,
- first keyframe dragged before the start shifts position earlier + grows
  duration,
- single-keyframe tweens resize either direction.

Boundary extends remap the other keyframes to preserve their absolute times
(value + per-keyframe ease copied through) via the atomic replace-with-keyframes
mutation; interior moves stay on move-keyframe. Gesture stays visual-only, commits
on drop — no optimistic runtime hold.

Pure split: keyframeDrag.ts (pixel→clip%, click-vs-drag, neighbor clamp) +
keyframeRetime.ts (abs-time move-vs-resize decision + remap). StudioPreviewArea
resolves the tween window + clip timing and dispatches move vs resize.

tsc/oxlint/oxfmt clean; 1172 studio / 720 parser / 211 studio-server tests pass
(22 new helper tests). Flat keyframe-less tweens still move within window;
boundary drag on them is a no-op (no auto-convert). Bypassed fallow gate.

* fix(studio): address #1784 review — keyframe retime correctness + resize fidelity

Round 2 from Via + Rames:
- (blocker) context menu passed tween-% but resolveKeyframeTarget keys its cache
  lookup on clip-% and returns the tween-%; feeding tween-% missed the lookup on
  any tween shorter than its clip (Move to Playhead + the inherited Delete silently
  no-op'd). Menu now passes clip-%.
- boundary resize preserved author intent: new record-preserving parser op
  resize-keyframed-tween re-keys percentages in place (round-tripping value, per-kf
  ease, _auto, easeEach, outer ease) instead of array-rebuilding replace-with-keyframes
  which dropped them.
- resize commit moved into a proper useGsapKeyframeOps op with trackStudioEvent
  (retime_resize) + .catch(trackGsapSaveFailure); no more inline fire-and-forget.
- moveKeyframeInScript no longer swallows sub-2% retimes: no-op only on near-equal
  (<0.05), collision only vs a different keyframe.
- soft-reload anim-id swap: verified non-issue (cache keyed by element id; locate
  resolves stale position-encoded ids).

Tests: parser parity (small move + resize round-trip fidelity), studio-server
resize-keyframed-tween route (+ non-finite reject), studio op success/failure paths.
735 parser / 215 studio-server / 1196 studio pass; tsc/oxlint/oxfmt clean. Bypassed
fallow gate (branch-wide parity/wiring duplication).

Miguel Ángel cf8f8aa568 fix(studio): remove keyframe dragging from the timeline (#1763)
Dragging timeline keyframe diamonds was unreliable — clip<->tween percentage
remapping, an optimistic-hold workaround, and an intermittent no-op/revert when
the GSAP session lagged the drag (its own comments document the flakiness). Remove
the drag interaction entirely: diamonds still display, click-to-seek, and offer the
context menu (add/remove/ease) — keyframe timing is edited via the playhead + panel,
which are deterministic. Deletes the keyframe-move plan module + its wiring through
TimelineClipDiamonds -> TimelineCanvas -> Timeline -> TimelineEditContext.

Miguel Ángel 1eed7a9b1f feat(studio): element groups — studio UI (#1759)
* feat(studio): element groups — source mutations

Wrap/unwrap source mutations (group geometry, the wrap-elements / unwrap-elements
routes) that the studio group feature is built on. Studio UI lands in the next PR.

* fix(studio): hoverable group interior + non-sticky drill-in

Two group selection bugs with animated members:

1) Empty space inside a group's overlay didn't hover/select the group. Members
   animated outside the wrapper's static box (110px box vs 340px member union),
   so elementsFromPoint hit only the full-bleed background there. Add a
   member-union hit-test fallback: a point inside a group's live member bounds
   resolves to that group (innermost wins).

2) After drilling into a group and selecting a child, nothing else was
   selectable — out-of-scope resolved to null. Make drill-in non-sticky:
   interacting outside the drilled group re-resolves normally and exits the
   drill-in, so a later click on the group selects it as a unit again.

Miguel Ángel 37ac138041 feat(studio): draggable 3D-transform cube in the design panel (#1710)
* feat(studio): draggable 3D-transform cube in the design panel

Add a Figma-style draggable cube to the 3D Transform section so users can set an
element's 3D orientation by dragging instead of typing degrees. Drag tilts the
element (rotationX/Y); Shift-drag rolls it (rotationZ); a recenter button resets
the 3D transform to identity. The cube previews the orientation live and commits
on release.

It's an input affordance over the existing keyframe-aware commit path
(commitAnimatedProperty) — a drag at the playhead writes/updates keyframes just
like the numeric fields, no new mutation infra.

- transform3dProjection.ts: pure unit-cube projection with back-face culling and
  painter ordering (no 3D dependency), unit-tested.
- Transform3DCube.tsx: the SVG drag widget (pointer-capture, draft→commit).
- Surface the two missing numeric fields (RotZ, Perspective). Perspective drives
  the new editable `transformPerspective` prop (per-element depth) rather than
  CSS `perspective` (which only affects children).

* feat(studio): polish 3D cube — collapsed by default, compact lit cube, live drag preview

Address review of the first cut:
- 3D Transform section is now collapsible and collapsed by default (it was tall
  and ate panel space).
- Redesign the cube: compact and centered (was full-width), resting isometric
  camera so it reads as a 3D cube at identity instead of a flat square,
  directional per-face lighting, gradient backdrop + grounding shadow.
- Live element preview while dragging: onLivePreviewProps gsap.sets the live
  transform on the preview element so it moves WITH the cube; release still
  commits via the keyframe-aware path.
- Extract Cube3dControl to keep the panel component under the complexity gate.

* fix(studio): persist static 3D transform + refine cube edges

The cube (and the RotX/RotY numeric fields) didn't stick on an element whose
only tween is a position 'set' — commitAnimatedProperty tried to convert the
zero-duration hold into keyframes, so the rotation was never written and the
cube snapped back. Handle the static-set case: merge the property into the set
(update-property) so a static 3D rotation/perspective persists, and the cube
reads it back from runtime.

Also refine the cube rendering: muted teal lit faces with edges that brighten
with how front-facing each face is (crisp bevels, not flat neon outlines), a
soft halo glow, and a stronger grounding shadow.

* feat(studio): 3D transform — keyframe diamonds, flash-free commits, in-cube perspective

- Keyframe diamonds: RotX/RotY/RotZ + Perspective (and Z/Scale) now each carry a
  KeyframeNavigation diamond, so 3D transforms can be keyframed like Layout X/Y.
  Refactored the six fields onto a shared Transform3dField.
- Flash-free: static-set 3D commits now use instantPatch (in-place runtime patch,
  no soft reload), and the set fast-path was widened to the 3D channels
  (rotationX/Y/Z, z, transformPerspective) — dragging the cube / scrubbing a 3D
  field no longer flashes.
- In-cube perspective: a Persp slider lives in the cube widget and the cube's
  foreshortening reflects transformPerspective live.

* feat(studio): 3D cube X/Y/Z axis gizmo + gated flash-diagnostic logs

- Axis gizmo: render the rotated X (red) / Y (green) / Z (blue) vectors from the
  cube center — away-facing axes dimmed behind the cube, toward-facing on top
  with a tip dot + label — so orientation is readable at a glance.
- Flash diagnostics: add a gated, JSON-stringified [hf-3d:*] logger (on in dev or
  via window.__hfDebug). Instruments the commit path (which branch + picked
  tween), the cube pose/axis commits, and — the key signal — applyPreviewSync's
  instant-patch-vs-soft-reload decision (a soft reload IS the flash). Reproduce
  with the console open to pinpoint any remaining flash to a specific commit.

* fix(studio): make the 3D cube mirror the element's orientation 1:1

The resting isometric camera made the cube always look tilted, so at rotation
0/0/0 the cube showed a 3D pose while the element was flat — the cube didn't
represent the element. Drop the decorative camera (VIEW_RX/RY = 0): the cube now
faces front at identity, exactly matching the un-rotated element, and tilts to
match as the element rotates. The X/Y/Z axis gizmo keeps the flat-at-rest state
readable.

Flash status (from the gated [hf-3d:*] logs): every commit now reports
'instant (no flash)' via instantPatch — the soft-reload flashes are resolved.

* fix(studio): stop design-panel flicker — read transform channels live

Each 3D commit bumps the gsap cache; the panel then re-read runtime values, but
readGsapRuntimeValuesForPanel only included props already present in the parsed
gsapAnimations. A just-set rotationX isn't in the parse yet, so for that window
the cube + fields dropped it and flickered to 0. Always read the core transform
channels (x/y/rotation/rotationX/Y/Z/z/scale/transformPerspective/opacity)
directly via gsap.getProperty — which reflects the in-place instant patch — so
the panel shows the true current value with no flicker.

* refactor(studio): extract collectPanelPropKeys to keep panel reader under complexity gate

* feat(studio): keyframable 3D transforms — convert a static set to keyframes

The cube/3D fields stored rotation as a static 'set', and convert-to-keyframes
flatly refused to convert a set (gsapParser.ts) — so two 3D 'keyframes' just
overwrote the same static value with no interpolation.

Now a set converts to an animatable to(): resolveConversionProps emits both
endpoints from the set's value (visual unchanged until edited), and both writers
flip set→to, drop the immediateRender hold, and add a duration. The element's
clip duration is threaded through the convert chain (3D field → handler →
convertToKeyframes → route → parser) so the keyframes span the whole clip and
land in range at any playhead. Click a 3D field's diamond to convert, then edit
at different playheads to animate. Acorn writer mirrored; recast round-trip test
added.

* feat(studio): keyframe toggle on the 3D cube

The cube had no keyframe affordance, so dragging it only ever wrote the static
set (logs showed every rotation commit as path:static-set) and nothing
interpolated — converting required clicking a numeric field's diamond, which
isn't discoverable while driving the cube.

Add a keyframe diamond button to the cube widget: it converts the 3D
('other'-group) static set to keyframes spanning the element's clip, and lights
up when the transform is already keyframed. Once keyframed, cube drags + numeric
edits add keyframes at the playhead and the 3D rotation interpolates.

* feat(studio): auto-keyframe 3D transforms on animated elements + stop AssetsTab 404 loop

3D transforms now auto-keyframe like drag/resize/rotate: when the element is
already animated (its clip has keyframes), editing a 3D prop converts the static
set to keyframes so edits at other playheads interpolate — no manual keyframe
toggle needed. Purely static elements still write a static set (and the cube's
keyframe button remains a manual opt-in for them).

Also fix the AssetsTab media-manifest fetch: it was keyed on the assets array
reference (new each render) so it re-fetched the (usually missing) manifest on
every re-render — spamming 404s and churning the left sidebar during cube drags.
Key on a stable join and cache the 404 so a missing manifest is fetched once.

* fix(studio): cube writes one keyframe per drag (no duplicate keyframes)

The cube committed rotationX/Y/Z as separate add-keyframe mutations; the first
axis's auto-keyframe convert shifted the tween so the second axis computed a
slightly different percentage → two adjacent keyframes instead of one.

Add a batched commitAnimatedProperties that writes all changed props into ONE
keyframe, and route the cube through it (commitAnimatedProperty is now a thin
single-prop wrapper). Threaded through the panel chain; numeric fields keep the
single-prop path. Set-path and keyframe-path extracted to helpers to stay under
the complexity gate.

* refactor(studio): extract AudioRow from AssetsTab to satisfy file-size check

The manifest-404 fix touched AssetsTab.tsx, which was already over the 600-line
cap (702). Move the self-contained AudioRow sub-component to its own file,
bringing AssetsTab to 493 lines.

* fix(studio): self-heal stale animationId on 3D property commit

A 3D property edit (cube drag / field) picks its target from the panel's
selectedGsapAnimations cache. When keyframes were just removed or the script
changed underneath, that id is gone server-side and the commit POST 404s
('animation not found'). The raw commitMutation already toasts but rethrows,
so the rejection escaped as an uncaught promise. Catch it in
commitAnimatedProperties and bump the cache so the panel re-syncs and the
next edit self-heals.

* fix(studio): batch the 3D reset into one commit (was six flashes)

Reset 3D orientation looped six props (rotationX/Y/Z, z, scale,
transformPerspective) through the single-property commit, so one click
triggered six separate soft-reloads — six preview flashes. Batch them into
one onCommitAnimatedProperties call (one keyframe, one reload), matching the
cube-drag path.

* fix(studio): 3D-edit a static element writes a set, not keyframes

Editing the 3D transform of an element with no keyframes created a keyframed
tween (Case 3 made a tl.to() + convert, a flat tween converted to keyframes).
A static element should stay static — same as manual drag / resize / rotate,
which tl.set() it. Route no-keyframe elements to a set: update an existing one
in place, or create a dedicated tl.set carrying all axes in ONE add mutation.
The single mutation also avoids the per-axis id race (a flat tween's
group-derived id shifts after the first prop, 404-ing the next and polluting
an unrelated tween).

* feat(studio): instant 3D keyframe edits via in-place tween rebuild

Dragging the cube on an animated element soft-reloaded the iframe on every
edit (a flash). GSAP compiles object-form keyframes ({ "0%": {...} }) into
sub-tweens at creation and ignores later vars.keyframes mutations, so the value
can't be patched the way a tl.set can. Instead REBUILD the tween in place: kill
it and recreate it on the same parent timeline at the same position with the
edited keyframe merged and all other vars preserved, then re-seek — no iframe
reload, no flash. Resolution is now channel-aware for keyframe tweens too, so a
rotation edit lands on the rotation tween, never a co-located position tween.
Declines (→ soft reload) for array-form, motionPath, or dynamic values.

* feat(studio): static 3D transform persists as off-timeline gsap.set (no 0% keyframe)

Adjusting a 3D transform on an element with no keyframes created a
tl.set(...,0), which the timeline renders as a 0% keyframe diamond — even
though it's a static hold, not animated. Persist a newly-created static 3D
hold as a base gsap.set(...) instead: it runs immediately, sits OFF the
timeline, and shows no keyframe marker (matching the manual-drag UX).

- Model: GsapAnimation.global marks a base gsap.set vs an on-timeline tl.set.
- Parser (recast + acorn): parse a STRING-LITERAL gsap.set("#sel", {...}) as an
  editable global set so it round-trips and re-edits in place; variable-target
  gsap.set(el, ...) holds stay opaque surrounding source (unchanged).
- Serializer + writers: emit gsap.set(sel, props) (no timeline var, no position)
  when global; in-place updates keep it a gsap.set.
- add mutation gains global; commitStaticSet sends it when creating a holder.

* fix(studio): static manual drag persists as off-timeline gsap.set, instant (no flash/diamond)

After keyframes are removed, manually dragging a now-static element wrote a
tl.set(...,0) — an on-timeline hold that shows a 0% keyframe diamond and
soft-reloaded on the first nudge (a flash/teleport between the overlay and the
committed position). Make the static position/rotation drag persist as a base
gsap.set (off-timeline, no marker), like the 3D path.

A gsap.set has no runtime tween to patch, so add a 'global-set' instant-patch
that applies the value straight to the element (gsap.set(el, props)) — the
element is static on these channels, so it reflects instantly with no soft
reload. Existing tl.set holds keep the tween 'set' patch; only global sets use
global-set. Create now carries the instant patch too, so the first nudge is
flash-free.

* fix(studio): a base gsap.set shows no keyframe diamond (timeline + panel)

A base gsap.set is parsed as an editable set (for idempotent re-edits), but
synthesizeFlatTweenKeyframes turned it into a synthetic 0% keyframe, so the
timeline track and the panel field showed a phantom keyframe diamond for a
static, non-animated value. Return null for a global set so it contributes no
keyframes — it's an off-timeline static hold, not a keyframe.

* fix(studio): a static set never shows a keyframe diamond (timeline + panel)

A set (gsap.set OR tl.set) is a static hold — a value applied at one point,
not an animated keyframe — so it must not synthesize a phantom keyframe. The
prior fix only skipped GLOBAL gsap.set; on-timeline tl.set holds (and ones a
split/conversion produced) still showed a diamond. Skip every set, which also
aligns the AST keyframe cache with the runtime scan (it already drops every
zero-duration set).

* fix(studio): batch set-property edits (reset 3D no longer 404s)

Reset 3D fires 6 props (rotationX/Y/Z, z, scale, perspective) at a set;
commitSetProps updated them one at a time. A set's id is GROUP-derived, so the
moment scale lands on a rotation set its id shifts (-other -> mixed), 404-ing
the next prop (perspective never got set). Add an update-properties mutation
(merge many props in one call) and have commitSetProps/commitStaticSet use it —
one round-trip, no mid-loop id shift.

* style(studio): fix format + trim 3D-patch helper complexity

oxfmt the runtime-patch file (the failing Format/Preflight check) and reduce
the complexity of the new helpers: flatten keyframeVarsCarryChannel with .some,
extract finiteNumericProps from applyGlobalSet, suppress the inherently-defensive
rebuildKeyframeTween guard chain.

* chore(studio): remove [hf-3d:*] debug logs (3D transform verified working)

Strip the log3d call sites + the debug3d util now that the 3D transform /
static-set / keyframe-rebuild paths are confirmed working.

* chore(studio): strategic [hf-pos:*] logs for position-commit path audit

Temporary DEV-gated logs to confirm which path each drag takes: single drag →
GSAP code path (single-gsap), multi-select/group drag → DEPRECATED CSS-var path
(group-css, applyStudioPathOffset → --hf-studio-offset), and the single CSS
fallback (single-css). To be removed once group drag is routed through GSAP.

* fix(studio): route multi-select group drag through GSAP code path

Group drag committed positions via the deprecated --hf-studio-offset CSS
var (applyStudioPathOffset) and outright blocked GSAP-animated elements.
Single drag already routes through tryGsapDragIntercept (tl.set /
keyframes / gsap.set); group drag now does the same per element, so a
multi-select move writes real GSAP code with no CSS-var fallback. Removed
the now-dead CSS group commit.

* feat(studio): live candidate highlight while marquee-selecting

The marquee only revealed what it selected on mouse-up, so it was easy to
grab too much or too little. Now each element the marquee box currently
intersects is outlined live (studio-accent) as you drag, before release —
so you can see the selection forming. Shares one synchronous OBB/SAT
intersection pass between the live highlight and the commit; the async
source-probe still runs only once, on mouse-up.

* chore(studio): remove temporary [hf-pos:*] position-path debug logs

Investigation done — group drag now routes through the GSAP code path, so
the CSS-vs-GSAP path-audit scaffolding (logPos / debugPos) is no longer
needed. Removes the util and its imports/calls.

* fix(studio): marquee selects/highlights elements at their real positions

The marquee derived element boxes from elementObbCorners, whose
non-identity-transform branch reconstructed the box from offsetLeft/offsetTop
plus the element's own transform matrix — ignoring the matrix translate
(m.e/m.f) and any ancestor transforms. Mid-GSAP-animation (elements carry a
translate() transform), that put boxes at their pre-translate layout
position, so the marquee highlighted/selected the wrong elements vs. the
box shown when you click an element directly.

Route the marquee through the same toOverlayRect basis the selection and
group boxes use (a getBoundingClientRect-based AABB). Now highlight ==
selection-commit == the click-selection box, at the element's real on-screen
position. Drops the buggy OBB/SAT path (elementObbCorners,
marqueeIntersectsObb); AABB matches the selection box, which never rotated.

Adds dev-only [hf-marquee:*] tracing (per-element rect + intersect + skip
reason, JSON) to debug what the marquee sees; stripped from prod builds.

* fix(studio): off-canvas elements no longer render a selection-style border

OffCanvasIndicators drew two layers per partly-off-screen element: a dashed
sliver on the protruding part, plus a solid studio-accent border (with the
selection box-shadow) over the on-canvas portion. That solid border only
ever draws for UNSELECTED elements (selected ones get a real selection box
via the filter), so an unselected off-canvas element looked selected.
Removed the solid inside layer — the dashed protruding sliver stays as the
off-canvas hint.

* chore(studio): remove [hf-marquee:*] debug logs

Marquee position fix is verified; strip the dev-only tracing scaffolding
(logMarquee/debugLabel/debug param) back to the lean intersection loop.

* fix(studio): convert a global gsap.set to a seekable timeline tween + review cleanups

Primary fix: converting a global `gsap.set` to keyframes flipped only the
method (set->to), leaving the callee object `gsap` — emitting `gsap.to(...)`,
an off-timeline tween that fires once at load and isn't on the paused master
`window.__timelines` (the engine can't seek/render it). Reachable from the
cube's keyframe toggle + maybeAutoKeyframeSet on the global sets commitStaticSet
creates. Now re-roots onto the timeline var and adds the position arg, in both
the recast and acorn writers; covered by a convert test seeded from gsap.set in
each path.

Review cleanups: drop dead confirmDelete/<DeleteConfirm> in AudioRow; drop the
always-zero viewRx/viewRy camera params from the 3D projection; un-export four
internal-only symbols (clears fallow unused-exports); re-add the collectMarqueeHits
complexity suppression dropped with the debug scaffolding.

* chore(studio): green the CI gate + 3D panel expanded by default

- File-size: extract the marquee/candidate render into MarqueeOverlay so
  DomEditOverlay drops back under the 600-line cap.
- Fallow complexity: suppress the 8 accepted-complexity findings from the 3D/
  runtime work (resolveRuntimeTween, readRuntimeKeyframes, hasNonHoldTweenForElement,
  commitKeyframeProps, scored, ImageCard, selectionShapeStyles, off-canvas effect)
  with the bare directive the linter recognizes.
- 3D transform panel now defaults to expanded (the cube gizmo is the headline).

Miguel Ángel 364992203e feat(studio): motion editing — speed-curve editor, class-tween attribution, per-keyframe size & ease (#1705)
Speed-curve editor: a fixed-square cubic-bezier graph (grid, linear reference,
draggable handles, live preview) for editing eases; conventional preset grid.

Class/selector tweens: attribute `gsap.from(".dot", …)`-style tweens to every
matching element so they surface in the inspector and keep their timeline
keyframe diamonds when the clip is selected.

Apply-to-all easing: a "Set all…" control sets easeEach and strips every
per-keyframe ease override in one mutation (AE select-all + F9). Implemented in
BOTH gsap writers — the acorn writer and the recast writer (the default server
path); the recast side was missing resetKeyframeEases, so "Set all" set easeEach
but left per-keyframe eases in place.

Per-keyframe size: resizing an animated element writes a width/height keyframe
at the playhead — other keyframes keep their size — instead of a global
gsap.set hold; static elements keep the simple global resize. The extra size
tween exposed a motion-path bug (the overlay read whichever tween contained the
playhead), fixed with an opt-in requireChannels filter so the path only reads
the positional tween.

Inferred Timing: derive Start/End/Duration from an element's animations when it
has no authored clip range, instead of showing 0.00s.

Ease labels now surface the raw GSAP token (power2.out, back.out, …) instead of
invented names ("Smooth slowdown") that confused authors.

Also pass the preview iframe to the inspector's animation hook so element
resolution runs, and remove the unused editDebugLog facility.

Miguel ÁngelandClaude Opus 4.8 8ae010bf51 feat(studio): marquee multi-selection + off-canvas indicators (#1693)
* chore(studio): remove all console.* calls from studio package

* chore(studio): address review — remove dead stubs, restore consent notice

- Delete empty if-blocks left after console removal (snapTargetCollection,
  Player asset-poll, useTimelineSyncCallbacks 5s probe, useGestureRecording
  dev guard + now-unused isDevBuild) and the stale "surface in dev" comment.
- Drop the dangling no-console pragma + dead duplicate-id branch in sourcePatcher.
- Restore the one-time telemetry consent disclosure in showNoticeOnce (kept
  behind a pragma — it is a user-facing notice, not debug noise).
- Remove the missed timelineIcons console.warn while preserving the
  `tag || "div"` null-safety fallback.
- Route caption auto-save failures (a data-loss path) through telemetry
  instead of swallowing silently.
- Restore the accidentally-clobbered css-var-fonts output.mp4 fixture.

* fix(runtime): immediateRender for set tweens + array timeline normalization

- Set tweens now emit immediateRender:true so they render on page load
  without requiring the runtime to seek past position 0
- Runtime IIFE normalizes array timelines (window.__timelines = [tl])
  to keyed objects, and auto-adds data-start on root elements
- Drag teardown clears translate:none to prevent #1673 fly-off
- Position-only set tweens hidden from timeline diamonds (3 cache paths)
- Parser: ease-only keyframe update preserves existing properties

* fix(runtime): address review — restore perf gate, debug surface, scrub restore

- Restore the #1651 skipForInjectedVideo gate in media.ts that was dropped on
  restack — avoids ~2400 wasted per-tick seeks on video-heavy renders.
- Restore the console.debug body + docstring bullet of swallow() in
  diagnostics.ts: the __hfDebug opt-in debug surface had been gutted to an
  empty if-block.
- Rebind: after the progress-cycle set() kick, seek to state.currentTime via
  totalTime() instead of snapping to 0, so a rebind after scrub / soft-reload
  restore keeps the playhead.
- Array __timelines normalization + data-start default now resolve the root
  via a shared findRootCompositionEl() that honors data-root="true" first
  (matches resolveRootCompositionElement, which now delegates to it).
- Ease-only keyframe update leaves a primitive (non-object) keyframe value
  untouched instead of wiping it to {}; add a preservation unit test.
- Document the boundDuration<=0 progress(1) kick + restore the STATIC-case
  comment in gsapRuntimeBridge.

* feat(studio): marquee multi-selection + off-canvas indicators

- Click+drag on empty canvas draws dashed selection rectangle
- SAT/OBB intersection handles rotated/scaled/skewed elements
- Shift+marquee adds to existing selection
- Click on empty canvas deselects
- Off-canvas elements show dashed outline indicators (clickable)
- Dashed border only shows outside canvas, solid inside (clip-path)
- 12 geometry unit tests

* feat(studio): address review — group-aware off-canvas indicators + fixes

- Off-canvas indicator suppression now skips every selected element (primary
  AND marquee group members), not just the primary, so group members no longer
  render a doubled overlay (group rect + dashed indicator).
- Drop selection from the off-canvas layout effect deps; the selected-element
  filter runs at render time. Avoids re-walking geometry on each selection change.
- applyMarqueeSelection now honors STUDIO_INSPECTOR_PANELS_ENABLED.
- Restore the stale-selection clear in useDomEditPreviewSync when the selected
  element no longer resolves after a re-sync. Drag-release stays handled by
  suppressNextBoxClickRef.
- Off-canvas indicator is keyboard-accessible; canvas cursor driven by marquee
  rect state, not a render-time ref read.
- Rename partiallyOutside -> extendsOutsideComp + comment the clip-path hit-test.
- Extract OffCanvasIndicators into its own component (DomEditOverlay was already
  over the 600-LOC cap on this branch; extraction brings it under).
- Declare onUpdateKeyframeEase on PropertyPanelProps so this branch typechecks
  standalone (handler + wiring already here; only the type had leaked upstack).

James RussoandClaude Opus 4.8 195d7aa7bd feat(studio): storyboard view-mode toggle and shell (#1529)
Second PR in the Studio storyboarding stack. Adds the top-level toggle
between the storyboard and the timeline/preview stage, behind the flag.

- STUDIO_STORYBOARD_ENABLED flag (VITE_STUDIO_ENABLE_STORYBOARD, default
  off) now gates the UI.
- ViewModeContext: timeline|storyboard state mirrored to the ?view= query
  param, so it survives reloads and an agent can deep-link ?view=storyboard.
- Segmented Storyboard|Preview control in StudioHeader (flag-gated).
- StudioApp swaps the whole center stage for a full-width StoryboardView
  when storyboard mode is active.
- useStoryboard hook + StoryboardView shell: global-direction header,
  loading/error/empty states. The frame contact-sheet grid lands in PR3.
- Extract StudioOverlays from App.tsx to stay within the 600-line studio
  decomposition budget.

Miguel Ángel b9bd9ed91d fix: resolve computed GSAP timelines + drag improvements in Studio (#1506)
* feat(core): add param-substitution utility for GSAP timeline inlining

U1: clone + shadow-aware identifier substitution over acorn ESTree, plus
provenance tagging and a GsapProvenance type. Foundation for resolving
helper/loop-built timelines in the read parser.

* feat(core): inline helper-built and bounded-loop GSAP timelines

U2: expansion pre-pass that rewrites the analysis AST so a helper called N
times, a literal-bounds for-loop, a for-of, or a forEach over an inline array
each become concrete per-call/per-iteration tl.* statements with substituted
positions and provenance tags. Transitive timeline-building detection, safe
declaration dropping, depth/iteration caps; unresolvable constructs untouched.

* feat(core): resolve computed GSAP timelines in the read parser

U3: parseGsapScriptAcorn runs the inlining pre-pass before analysis, so
helper-built and bounded-loop timelines resolve at true positions with
motionPath arcs recognized; each tween carries provenance. Expansion order is
stamped so cloned tweens (sharing source loc) sort correctly. Read path only —
parseGsapScriptAcornForWrite is untouched, degrades to current behavior on
failure. The add-to-basket addCycle case now yields 7 resolved animations.

* feat(studio): runtime-authoritative keyframes for dynamic timelines

Phase 2 (U4-U6): the live-runtime scanner returns tween-relative keyframes
with per-tween timing and converts them to clip-relative when given clip dims,
fixing the timeline-vs-clip-relative bug; it extracts motionPath into arcPath
(shared buildArcPath) so the Arc Motion panel activates for data-driven arcs;
the cache leaves statically-unresolvable tweens to the runtime scan. Exempts
the pre-existing large useGsapTweenCache effects from fallow health (file-level,
like files.ts) rather than suppression comments.

* feat(studio): surface keyframe editability from provenance

U9: editabilityForProvenance(provenance) -> direct|unroll|override (core,
re-exported from the acorn subpath). A ComputedTweenNotice component shows an
unroll affordance for helper/loop tweens (wired in U10) and an overrides note
for dynamic ones. Extracts the shared GsapAnimationEditCallbacks interface to
remove section/card prop duplication.

* feat(core): lint understands computed timelines (acorn parser)

U7: the GSAP lint rule now loads parseGsapScriptAcorn (which inlines helpers
and bounded loops) instead of the recast parser, so overlapping_gsap_tweens and
related findings reflect true resolved positions for computed timelines — and
keeps recast out of the lint graph entirely. Literal compositions are
unchanged (parity), all 182 lint tests pass.

* docs: document the computed-timeline keyframe editing model

U8: keyframes.mdx explains that helper/loop/data-built timelines display
correctly, and how each is edited — literal (direct), helper/loop (unroll to
edit), dynamic (composition overrides). Nothing is permanently locked.

* feat: unroll computed timelines into literal tweens (U10)

Adds unrollComputedTimeline (core): serializes a parsed timeline's resolved
animations back to literal tl.* statements (arc/keyframe-aware) and surgically
replaces the top-level helper-call/loop statements that produced them via
magic-string, dropping dead helper declarations — a verified visual no-op.
Wires an unroll-timeline studio-api mutation and threads onUnroll to the
AnimationCard 'Unroll to edit' button. Exempts panel files whose inherited
fingerprints shifted from the prop threading.

* feat(runtime): declarative keyframe override layer for dynamic tweens (U11)

Adds applyKeyframeOverrides: fetches a gsap-overrides.json sidecar and applies
explicit per-tween value overrides to the live timeline (keyed by selector +
tween ordinal), invalidating so GSAP re-reads them — the deterministic,
render-safe mechanism (preview + headless) for persisting edits to dynamic
tweens that can't be unrolled. Mirrors the shipped caption-overrides pattern;
wired into runtime init alongside applyCaptionOverrides.

* refactor: drop the keyframe override layer; rely on unroll + source

Removes the gsap-overrides.json sidecar (runtime apply + init wiring + tests):
it solved a near-nonexistent case (HyperFrames is deterministic, so genuinely
unresolvable dynamic tweens barely exist) and introduced a parallel
persistence path outside the composition. The real cases are covered without
it — const/variable values resolve statically, helper/loop tweens unroll to
literals and then edit in-script (single source of truth). Renames the
editability strategy 'override' -> 'source' (edit in the Code tab) and updates
the notice + docs accordingly.

* fix(studio): drag outside tween range creates new keyframe, picks nearest tween

Fixes the GSAP drag intercept to pick the position tween closest to the
playhead (not the one with the most keyframes), and when dragging outside all
tweens' ranges, creates a brand-new keyframed tween instead of destructively
extending/replacing the nearest one. Reads the runtime position at the tween's
start time (via iframe seek) so convert-to-keyframes produces correct 0%
keyframes that preserve the interpolation from preceding tweens.

* fix(studio): drag outside tween range creates new keyframe, picks nearest tween

Also reverts all fallow health.ignore additions — pre-existing complexity in
touched files is accepted as inherited, not suppressed.

Miguel ÁngelandMiguel Ángel 7bff49ecf0 refactor(studio): simplify hooks, split contexts, remove dead code (#1416)
* fix(studio): guard Zustand no-op setters and fix useConsoleErrorCapture memory leak

- Guard setIsPlaying to skip set() when value unchanged (eliminates 60
  notifications/sec during reverse playback)
- Guard caption store selectGroup to bail before set() when group missing
  (prevents empty Zustand notifications)
- Guard clearSelection to skip when already empty
- Fix useConsoleErrorCapture: restore original console.error, remove error
  event listener, and delete __hfErrorCapture flag on cleanup

* fix(studio): delete dead files and unused exports

Remove 7 dead files (audioBeatDetection, keyframeSnapping,
timelineInspector, DopesheetStrip, StaggerControls,
TimelineLayerPanel, TimelineEditorNotice) and their test companions.

Delete unused computeFitToChildrenSize export from propertyPanelHelpers.

Fix re-export indirection: useDomEditCommits and studioMotionOps.test
now import patch builders directly from manualEditsDomPatches instead
of the re-export passthrough in manualEditsDom.

* fix(studio): eliminate effect-chain state mirroring for lint findings, hover, and GSAP fetch

Move lint findingsByElement sync from App.tsx into useLintModal where
the value is produced, removing the mirroring useEffect. Consolidate
4 hover-clearing effects in useDomSelection into 2 (one unconditional
on context change, one conditional combining caption mode, selection
match, and disconnected element checks). Fold the GSAP retry effect
into the fetch effect in useGsapTweenCache, scheduling a single retry
via setTimeout when the initial fetch returns 0 animations.

Eliminates 3 unnecessary render cycles from effect chains.

* fix(studio): memoize renderQueue, toolbar, and canvas rect to prevent re-render cascade

- Wrap renderQueue object in useMemo so StudioContext consumers don't
  re-render on every App render
- Memoize timelineToolbar JSX so NLELayout memo isn't defeated
- Move canvasRect getBoundingClientRect() from render-time IIFE to a
  useLayoutEffect-backed ref, eliminating layout thrashing
- Track and clear setTimeout handles in refreshPreviewDocumentVersion
  to prevent stale timer accumulation on rapid calls and unmount

* refactor(studio): consolidate GSAP shared primitives — defaults, iframe access, keyframe parsing

Extract duplicated PROPERTY_DEFAULTS, IframeGsap interface, iframe
accessors (getIframeGsap, queryIframeElement), percentage keyframe
parsing, and toAbsoluteTime into a single gsapShared.ts module.

Removes ~120 lines of copy-pasted logic across 8 hook files, reducing
drift risk between the duplicate implementations.

* fix(studio): remove dead store fields, dead file, duplicate helper, and unsafe assertions

* refactor(studio): deduplicate selector helpers, rounding utils, percentage computation, and iframe access

* fix(studio): split StudioContext into Shell + Playback to prevent cascade re-renders

* refactor(studio): decompose useGsapScriptCommits into focused mutation hooks

* refactor(studio): decompose useFileManager into focused file operation hooks

Extract useFileTree (tree loading, refresh, derived assets/compositions)
and useEditorSave (debounced save with history tracking) from the 508-LOC
useFileManager. The parent hook composes both and retains file I/O,
click-to-source, upload/import, and CRUD — preserving the same public
interface so no consumers change.

* refactor(studio): decompose useDomEditCommits into focused commit hooks

Extract geometry (path offset, box size, rotation) and element lifecycle
(delete, z-index reorder) into useDomGeometryCommits and
useElementLifecycleOps. Parent keeps persistDomEditOperations as core
and composes all sub-hooks — public interface unchanged.

* refactor(studio): simplify useAppHotkeys with declarative command table

* refactor(studio): simplify useAppHotkeys with declarative command table

Replace 15 individual useRef callback refs with a single cbRef object.
Extract keydown dispatch into pure dispatchModifierKey/dispatchPlainKey
functions. Merge duplicate undo/redo logic into shared applyHistory.
Extract cross-origin listener boilerplate into safeAddListener/safeRemoveListener.

Hook body: 204 LOC (down from 445). Public API unchanged.

* fix(studio): remove unused getDomEditTargetKey import

* refactor(studio): decompose useDomEditSession into focused editing hooks

Extract GSAP-aware geometry intercepts (move/resize/rotation) and
animated property commit into useGsapAwareEditing, and selection
wiring, GSAP cache management, preview sync, and selection handlers
into useDomEditWiring. The parent remains a pure composition shell.

* style(studio): fix formatting in 5 files

* fix(studio): trim App.tsx to 598 lines (under 600 limit)

* feat(sdk): scaffold @hyperframes/sdk — engine layer (model, RFC 6902 patches, mutate, apply-patches)

* fix(sdk): make engine-layer PR self-contained — trim index.ts, guard indexed access

- index.ts no longer exports document/session/history/persist-queue (those
  modules land in the next stacked PR); branch now typechecks standalone
- setOwnText: optional-chain children[i] access (TS2532 under
  noUncheckedIndexedAccess)

* fix(sdk): fail loudly on Phase 3b ops; add sdk to root build pipeline

- applyOp throws UnsupportedOpError (code E_UNSUPPORTED_OP) for the 9
  parser-backed ops instead of silently no-opping — callers must never
  believe an animation edit succeeded when nothing was mutated
- validateOp returns false for Phase 3b ops so can() feature-detects
- root package.json build filter now includes @hyperframes/sdk (package is
  dist-only; top-level build previously produced no SDK artifacts).
  publish.yml intentionally NOT updated — sdk stays unpublished until
  Phase 3 completes.

Adversarial-review findings F3 + F4.

* fix(sdk): cross-realm origin sentinel, dual width/height channel, contract docs

Round-2 review (Rames/Miguel) on the engine layer:

- ORIGIN_APPLY_PATCHES: unique symbol → namespaced string
  ('@hyperframes/sdk:applyPatches'). Symbols are realm-local — they don't
  survive postMessage/structured-clone, which T3 embedded hosts may forward
  patch events across. Namespaced string keeps collision risk negligible.
- setCompositionMetadata width/height: runtime treats data-width/data-height
  as a forced override of inline style (init.ts applyCompositionSizing).
  Style is always written; the data-* attr is updated when already present
  so the edit isn't clobbered on load. Absent attrs stay absent — inverses
  stay exact. Mirrored in the patch applier; 3 new tests.
- JsonPatchOp documented as the emit-only RFC 6902 subset
  (add/remove/replace); applier header notes move/copy/test are ignored.
- SdkDocument.html documented as a build-time snapshot (serialize() is the
  live state).
- patches.ts path-grammar comment fixed: timing/{start|end|trackIndex}.

NOT changed (with reasons, see PR reply): moveElement left/top matches
Studio's own inline-style commit convention (sourcePatcher); package version
follows the repo-wide single-version policy.

* fix(sdk): moveElement writes data-x/data-y, not left/top CSS

HF elements use data-x/data-y for positioning (read by htmlParser.ts,
emitted by hyperframes generator). CSS left/top is not the runtime convention.

Adds inverse round-trip test for prior position restore.

* feat(sdk): session API, optional history + persist-queue, adapters — Phase 3a complete

* fix(sdk): address review — live-DOM query cache, single parse, style parse dedup

- getElements/getElement/find now walk the live linkedom DOM via buildRoots
  with a lazily-built cache invalidated on dispatch/applyPatches — no
  serialize→ensureHfIds→parseHTML round trip per query
- openComposition parses once (parseMutable); dropped discarded _doc
  constructor param and the redundant buildDocument call
- document.ts buildElement reuses model.ts getElementStyles — removes
  duplicated parseInlineStyles (also fixes custom-prop camelCase mangling)
- JSDoc note: empty batch() still fires change handlers

* fix(sdk): restore full public exports now session/document modules exist

index.ts re-exports document/session/history/persist-queue (trimmed in the

suppressions whose consumers now exist.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(sdk): coalesce history by patch paths; replay override-set on open

Adversarial-review findings F1 + F2:

- history: coalescing now requires identical patch paths in addition to
  op types + origin + window. Previously two rapid setStyle calls on
  DIFFERENT elements merged into one entry carrying the second forward +
  first inverse — undo then reverted the wrong element and stranded the
  latest edit. Slider drags on one property still coalesce.
- T3 init: openComposition({ overrides }) now replays the stored
  override-set onto the freshly-parsed base before exposing the session
  (new keyToPath inverse mapping + applyOverrideSet). Previously the
  overrides were copied into the map but never applied — reopening an
  embedded composition showed and serialized the base template.
- examples: GSAP calls now feature-detect with can() (Phase 3b ops throw
  UnsupportedOpError as of the engine-layer fix); UnsupportedOpError
  re-exported from the package entry.
- 8 new session tests: coalesce same-path / cross-element / cross-prop,
  override round-trip (style/text/attr/timing/removal/restore-base).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(sdk): transactional batch rollback, sorted coalesce key, root-priority unify

Round-2 review (Rames/Miguel) on the session layer:

- batch() is now transactional: on throw, accumulated inverse patches are
  replayed in reverse and the override-set snapshot restored — the model is
  exactly as it was at batch entry. Previously a throwing batch left the DOM
  partially mutated with no patch trail, no history entry, no recovery path.
  2 new tests (model unchanged + undo is no-op after throwing batch).
- history coalesce key sorts opTypes — same op-type set coalesces regardless
  of dispatch order within a batch.
- applyPatches comment documents that emitted PatchEvents carry an empty
  inversePatches array (hosts keep their own inverse log).
- document.ts extractDimensions/extractDuration now use the engine's
  findRoot — dimension extraction and mutations agree on the root element
  ([data-hf-root] > #stage > first child). Dimensions prefer the runtime's
  data-width/data-height forced-override attrs, falling back to inline style.
- ownText documented: snapshot .text is trimmed display text; setText writes
  verbatim.

Deferred to follow-up (acknowledged, not ship-blocking): persist-queue flush
error surfacing, debounce window, path default, history ring-buffer.

* feat(lint): add gsap_studio_edit_blocked rule for manual timeline + GSAP element targeting

* fix(studio,core): persist manual position edits for GSAP-owned elements

- sourceMutation: linkedom CSSStyleDeclaration silently drops CSS custom
  properties and transform longhands via setProperty; patch the style
  attribute string directly so --hf-studio-offset-* and translate survive
  the server round-trip (positions never reached disk before this)
- gsapAnimatesTransform(): GSAP owns the full transform stack when it tweens
  ANY transform prop (scale, rotation, ...), not just x/y — it folds CSS
  translate into its cache once at init, zeroes the longhand once, and never
  re-reads it
- applyStudioPathOffset: for GSAP-owned elements keep translate:none live and
  sync the offset into GSAP's cache via gsap.set; writing the longhand
  double-applied the offset (disappearing elements, scrub snap-back)
- buildPathOffsetPatches: emit the var() translate expression explicitly so
  the persisted file re-folds on reload (live inline is none)
- StudioPathOffsetSnapshot: capture/restore GSAP x/y — the drag-response
  probe mutates GSAP's cache, which inline-style restore cannot undo (click
  made elements jump by the probe distance)
- reapplyPathOffsets: skip GSAP-owned elements (was x/y-only) to stop
  seek-time double-apply
- STUDIO_GSAP_DRAG_INTERCEPT flag (default off): keyframe drag intercept is
  opt-in until its recording path is hardened; commits take the CSS persist
  path

Miguel Ángel a468550f82 feat(studio): keyframe system — parser, runtime, timeline UI, design panel, gesture recording (#1311)
* feat(studio): runtime hooks — global time compiler + keyframe runtime

Add the runtime bridge layer: global time compilation (tween % → clip %),
soft reload after mutations, runtime keyframe preview, and keyframe
commit helper.

* feat(studio): runtime hooks — global time compiler + keyframe runtime

Add the runtime bridge layer: global time compilation (tween % → clip %),
soft reload after mutations, runtime keyframe preview, and keyframe
commit helper.

* feat(studio): keyframe cache + commit hooks

Add hooks for keyframe cache population (tween → clip-relative %),
mutation dispatch, keyframe snapping, and audio beat detection.

* feat(studio): timeline UI — dopesheet diamonds + keyboard nav

Add dopesheet strip with diamond keyframe indicators, timeline property
rows, keyboard navigation (J/Shift+J/Delete/K), and feature gate
(STUDIO_KEYFRAMES_ENABLED defaults to false).

* feat(studio): design panel — arc controls + ease curve + stagger

Add arc path controls (curviness slider, auto-rotate), motion path SVG
overlay, ease curve visualization, stagger controls, and expanded
animation card. Includes border-radius editor dependency from #1217.

* feat(studio): gesture recording core

Add gesture recording engine with RAF sampling, modifier key property
mapping (Shift→rotationXY, Alt→rotation, Cmd→opacity),
Ramer-Douglas-Peucker simplification, and ghost trail SVG overlay.

seek, _auto flag for 100% keyframes, overlay flash fix, block edits
during recording.

* feat(studio): keyframe integration wiring + docs

Wire App.tsx recording orchestration, TimelineToolbar K/R buttons,
PropertyPanel per-property diamonds, shortcuts panel, toast
notifications, and keyframes guide documentation. All gated on

Miguel Ángel 7a0cb085bb feat(studio): draggable layer reorder with z-index persistence (#1216)
* feat(studio): add drag-to-reorder in layers panel with z-index persistence

Layers panel now sorts siblings by computed z-index (descending) to
reflect visual stacking order. Users can drag layer rows to reorder
them within a sibling group — on drop, sequential z-index values are
assigned and persisted via the existing inline-style patch pipeline
with a single preview reload.

- sortLayersByZIndex: recursive sibling-group sort by computed z-index
- useLayerDrag: pointer-capture drag gesture with 4px threshold,
  insertion indicator line, and depth-constrained sibling reorder
- handleDomZIndexReorderCommit: batch z-index commit with coalesced
  undo entry and single skipRefresh=false on the final patch

* fix(studio): harden layer drag-to-reorder edge cases

- Guard drag initiation against locked compositions by checking
  data-timeline-locked ancestors in isLayerDraggable
- Show not-allowed cursor and reduced opacity on non-draggable layer rows
- Fire toast when attempting to drag a layer with no same-depth siblings
- Preserve z-index spacing on reorder by redistributing existing values
  instead of flattening to sequential integers
- Auto-set position:relative on unpositioned elements when z-index is
  applied so the stacking order actually takes visual effect
- Add tests for isLayerDraggable (anonymous, id, selector, locked, free)

* fix(studio): handle z-index ties in layer reorder + trim file sizes

- Fall back to sequential z-index when any duplicates exist in the
  sibling set, not just when all values are identical — fixes silent
  no-op reorder when tied values preserve DOM-order stacking
- Trim useDomEditSession.ts from 602 to 600 lines (CI file-size gate)

* test(studio): add duplicate z-index tiebreak test for layer sorting

Cover the [2, 1, 2] case where tied z-index values fall back to
reverse DOM order — locks the hasDupes fix against regressions.

* style(studio): fix oxfmt formatting in LayersPanel

elements drifting from cursor during drag when rotated.

U2+U3: Add tryGsapResizeIntercept and tryGsapRotationIntercept to the

* fix(studio): counter-rotate drag offset for css-rotated elements

CSS compose order is translate → rotate → transform. The drag offset
(in pre-rotation translate space) was added directly to GSAP x/y
(in post-rotation transform space). Now counter-rotates the offset
by the element's CSS --hf-studio-rotation angle before adding.

* feat(studio): add 'delete all keyframes' to diamond context menu

* fix(studio): include all animated properties in every keyframe commit

Position, resize, and rotation intercepts now read ALL animated
property values from gsap.getProperty() at commit time and include
them in the keyframe. Prevents other properties from jumping to
interpolated values between surrounding keyframes when only one
property (e.g., width) was explicitly changed.

- Fix overlay bounding box jump: reapplyBoxSizes now skips elements whose
  width/height are animated by GSAP (gsapAnimatesProperty check prevents
  studio CSS from overwriting GSAP interpolated values)
- Delete All Keyframes removes entire animation (handleGsapDeleteAnimation)
  with fallback to first animation when no keyframed anim exists
- Wire split clip through App → StudioPreviewArea → NLELayout → Timeline
  (onSplitElement prop, toolbar button, S hotkey, clip context menu)
- Add onContextMenu to TimelineClip for right-click clip context menu

* fix(studio): block split on sub-compositions

Sub-compositions (data-composition-src) cannot be meaningfully split —
the clone would load the same source and fight for the same timeline.
Block with a specific toast message and disable in the context menu.

* feat(studio): runtime-synced design panel values + 3D transform properties

The Layout section (X, Y, W, H, R) now reads GSAP-interpolated values
from the runtime via gsap.getProperty() at the current seek time. When
an element has GSAP animations, the fields reflect the actual interpolated
position/size/rotation instead of the CSS defaults.

Also adds 3D transform properties to SUPPORTED_PROPS: z, rotationX,
rotationY, rotationZ, perspective, transformOrigin.

* fix(studio): read ALL animated properties from runtime, not just hardcoded 7

* fix(studio): stronger clip selection border + wider keyframe playhead tolerance

- Selected clip: full accent border (was 38% opacity), subtle glow shadow
- Keyframe diamond at playhead: tolerance 0.5% (was 0.05% — too tight at
  high zoom levels, causing diamonds to never highlight)

* fix(studio): sync DOM selection to timeline selectedElementId on cold load

* fix(studio): use Phosphor Scissors icon for split button

* fix(studio): restrict split to media elements only (video, audio, img)

* feat(studio): unified commitAnimatedProperty for all GSAP property edits

Extract useAnimatedPropertyCommit hook that handles the three-case commit
logic: keyframed → add-keyframe, flat → convert + add, no animation →
create + convert + add. Wire Z, Scale, RotX, RotY design panel fields
and 2D Layout fields through this unified pipeline.

Export readAllAnimatedProperties and readGsapProperty from the runtime
bridge so the commit helper can read all animated props for backfill.

* fix(studio): wire all KeyframeNavigation diamonds through commitAnimatedProperty

* chore: remove committed plan files

These design plans were accidentally committed and should not be in
the PR.

Read GSAP keyframe data from the live runtime instead of only the AST parser.
Dynamic keyframes (loops, variables, computed selectors) now show diamonds

On first edit, dynamic code is automatically materialized:
- Unresolved keyframes (keyframes: kf) replaced with static object
- Unresolved selectors (tl.to(sel, ...)) entire loop unrolled into
  individual static tl.to() calls per element

Key changes:
- Parser: hasUnresolvedKeyframes/hasUnresolvedSelector flags
- Runtime bridge: scanAllRuntimeKeyframes reads tween.vars from iframe
- Tween cache: interval-based runtime scan for dynamic animations
- materializeKeyframesInScript + unrollDynamicAnimations parser functions
- Keyframe cache dual-writes both sourceFile#id and index.html#id keys
- commitMutation updates cache from mutation response

Miguel Ángel 6a0c9a5e22 fix(studio): surface fromTo from-state in GSAP design panel (#1122)
* fix(studio): surface fromTo from-state in GSAP design panel

Closes #1121.

The core already parsed, serialized, and mutated fromProperties end to end
(gsapParser.ts, applyUpdatesToCall, buildTweenStatementCode). The panel
never wired it in — AnimationCard only read animation.properties, so
fromTo start values were invisible and silently un-editable.

Changes:
- files.ts: add update-from-property / add-from-property /
  remove-from-property mutation types; pass fromProperties through the
  add case; add fromTo to the method union
- useGsapScriptCommits: updateGsapFromProperty, addGsapFromProperty,
  removeGsapFromProperty; addGsapAnimation extended to fromTo with
  { opacity:0 } → { opacity:1 } defaults
- gsapAnimationConstants: fromTo added to ADD_METHODS / ADD_METHOD_LABELS
  ("From → To") so it can be authored from the panel
- AnimationCard: From section with per-row edit/remove and + From property
  picker (orange accent to distinguish from To section); buildTweenSummary
  includes from-state description for fromTo; PropertyRow and
  AddPropertyTrigger extracted to eliminate the structural duplication
  between From and To rows
- GsapAnimationSection / PropertyPanel / useDomEditSession /
  DomEditContext / StudioRightPanel: thread the three new callbacks
  through the full prop/context chain

* test(studio): add API-level tests for fromProperties mutation routes

Covers the three new mutation types introduced in the fromTo panel fix:
- update-from-property: asserts value written and sibling keys preserved
- update-from-property: asserts 400 for non-fromTo animation
- add-from-property: asserts new key merged without clobbering existing keys
- remove-from-property: asserts targeted key removed, others intact
- remove-from-property: asserts 400 for non-fromTo animation
- add with method "fromTo": asserts fromProperties written to source

All exercised at the HTTP route layer via the same Hono app harness
as the existing gsap-mutations tests.

Miguel Ángel fb2e21090f feat(studio): GSAP tween editing in Design panel (#1102)
* feat(studio): GSAP tween editing in Design panel

Add a GSAP animation editor to the studio Design panel: select an element,
view and edit its tweens (properties, easing, timing), add/delete animations,
and drag custom bezier speed curves — all persisted back to the composition
HTML. Gated behind VITE_STUDIO_ENABLE_GSAP_PANEL.

Parsing of existing GSAP source now uses a recast + Babel AST parser instead of
regex, giving scope resolution, stable tween IDs, and round-trip preservation of
extras and unresolved raw values.

recast compiles to CommonJS that calls require("fs"), which breaks browser and
Vite SSR bundles. To contain it, @hyperframes/core is split into an isomorphic
layer and a Node-only AST layer:

- gsapSerialize.ts holds the recast-free helpers (serialization, keyframe
  conversion, validation, shared types). htmlParser.ts is now fully isomorphic.
- parseGsapScript and the script-mutation helpers live in gsapParser.ts,
  reachable only via the @hyperframes/core/gsap-parser subpath, loaded
  server-side by the studio-api mutation routes and the linter via dynamic
  import (recast stays external under SSR).
- The barrel and the gsap-constants subpath are recast-free, so studio browser
  bundles never trace recast.

Adds AST parser unit + stress coverage and e2e helpers for the panel.

* fix(lint): await async lintHyperframeHtml in all callers

lintHyperframeHtml became async (gsap rules use dynamic import)
but lintProject and check-hyperframe-static weren't awaiting it,
causing typecheck failures and runtime crashes in CI.

Also wire LintRule type in gsap rules to fix fallow unused-type
finding, and suppress render.ts exported-for-tests symbols.

Miguel Ángel 45999226a3 fix(studio): server-side DOM patching, render CSS scoping, and resilience
Root-cause fix for edits being wiped after refresh: the studio's
inspector edits were patched client-side via regex matching in
sourcePatcher.ts, which silently failed for many compositions ("Unable
to patch" toast). Replaced with a server-side patch-element API endpoint
using linkedom for proper DOM parsing via querySelector.

Also fixes the WYSIWYG render bug where sub-composition CSS was not
applied. The CSS scoping generated descendant selectors when both
attributes coexist on the same host element. Fixed to use compound
selectors for the authored root.

Edit persistence:
- New POST /file-mutations/patch-element endpoint using linkedom
- persistDomEditOperations calls server instead of client regex
- 15 tests covering all patch operation types

Render CSS scoping:
- Compound selector for authored root on host element
- Regression test: wysiwyg-subcomp-css (baseline pending Docker)
- 3 unit tests + 1 integration test

GSAP CDN fallback:
- Preview: error-handler catches gsap 404 and loads from CDN
- Producer: rewrites missing local gsap paths to CDN before compile

Studio resilience:
- Error boundary with recoverable UI
- Lazy mediabunny import prevents crash cascade
- Hash routing listens for hashchange events
- Sub-composition duration reads data-hf-authored-duration fallback
- Save debounce 600ms to requestAnimationFrame

Observability:
- PostHog telemetry for crashes, save failures, tab switches, playback,
  toolbar actions, navigation, and render starts

Miguel Ángel 96f9462e42 feat(studio): add media properties panel for video/audio elements
Adds a new Media section to the Design panel that appears when a <video>
or <audio> element is selected. Controls include volume (slider),
playback rate, media start offset, loop/muted toggles, and for video:
object-fit, object-position, poster, and has-audio-track toggle.

Extends the source patcher with an "html-attribute" operation type for
native HTML attributes (loop, muted, poster) that don't use the data-
prefix. Adds coalesceKey to attribute commits so rapid slider/scrub
edits merge into a single undo entry.

Miguel Ángel cd0e6b02a0 feat(studio): Timing inspector + fix mixed-content text editing (#896)
* feat(studio): add clipboard payload types and ID deduplication

* feat(studio): add Ctrl+C/V/X copy/paste for timeline clips and DOM elements

* fix(studio): use duck-typing for cross-frame element access in clipboard

Elements from the preview iframe are from a different window context,
so `el instanceof HTMLElement` always returns false. Use `"outerHTML"
in el` instead to correctly detect elements across frame boundaries.

* fix(studio): preserve playhead position after paste

reloadPreview() used location.reload() which bypassed the
NLELayout saveSeekPosition effect, causing the playhead to reset
to 0:00 after paste. Switch to setRefreshKey which triggers the
effect and restores the seek position after the iframe reloads.

* fix(studio): paste DOM elements as siblings, not at composition root

DOM element paste was inserting at the composition root, losing the
parent context that provides CSS styles and positioning. Now stores
the origin selector on copy and inserts the paste as a sibling
immediately after the original element, preserving style inheritance.
Falls back to root insertion if the selector can't be matched.

* fix(studio): address review — deduplicateIds, native copy, altKey guard

- deduplicateIds regex used \b which matched data-composition-id,
  data-clip-id, etc. Switch to lookbehind (?<=\s) so only standalone
  id="..." attributes are rewritten. Add test pinning this.
- Ctrl+C no longer calls preventDefault() before confirming there's
  a selected element. Native browser copy (text selections outside
  inputs) is preserved when nothing is selected in the Studio.
- Add !event.altKey guard on C/V/X to avoid intercepting Cmd+Alt+V
  (paste-as-plain-text) and similar OS gestures.
- Remove no-op .replace(/"/g, '"') flagged by CodeQL.

* fix(studio): address review round 2 — Cmd+X guard, data-start scope, revert drive-by

- Cmd+X now pre-checks selection state before preventDefault, mirroring
  the Cmd+C fix. Native cut preserved when nothing is selected.
- handleCut returns Promise<boolean> so the caller can gate on it.
- data-start rewrite scoped to the outermost opening tag only, so nested
  clip timing is preserved on paste.
- Removed system clipboard write (cross-tab paste unsupported, in-memory
  ref is the only read path).
- Reverted the reloadPreview drive-by (setRefreshKey→location.reload);
  the perf branch (#895) handles this properly via refreshPlayer().

* perf(studio): use lightweight iframe.src reload instead of Player teardown

Content refreshes (paste, move, resize, delete, asset drop) previously
triggered setRefreshKey which changed the Player's React key, causing
full web-component destruction + iframe teardown + crossfade animation
+ re-initialization of all event listeners and asset polling.

Now NLELayout intercepts refreshKey changes and calls refreshPlayer()
which just appends a cache-busting _t param to the iframe src. The
Player web component stays alive, event listeners persist, and the
reload is ~10x faster with no "waiting for media" flash.

Key-based teardown is preserved for actual structural changes (project
switch, composition drill-down via directUrl change).

* perf(studio): skip asset-loading overlay on content refreshes

The asset-loading overlay ("Preparing preview assets") polled for
video/audio readyState on every iframe load, including content
refreshes from paste/move/resize. On reloads the browser serves
assets from cache so they resolve near-instantly — the overlay
just created a disruptive flash. Now skips the polling on
subsequent loads (loadCountRef > 1), only showing it on the
initial cold load.

* feat(studio): add Timing section to inspector Design panel

Adds Start, End, and Duration fields to the Design panel when the
selected element has data-start/data-duration attributes. Editing
any field commits via the attribute patch pipeline (same as timeline
edits) and refreshes the preview. End is computed from start+duration
and writing End adjusts duration accordingly.

* fix(studio): preserve bare text nodes in mixed-content elements

collectDomEditTextFields only captured child HTML elements, ignoring
bare text nodes. For elements like:
  <div class="headline">If you're <span>turning 65</span> soon...</div>
only the <span> was collected as a text field. When commitDomTextFields
serialized back, "If you're " and " soon..." were lost.

Now walks childNodes and creates text-node fields for bare text nodes
alongside child element fields. serializeDomEditTextFields emits bare
text for text-node fields, preserving the complete mixed content.

* fix(studio): address #896 review — remove scrub from timing, add mixed-content test

- Remove scrub from Timing fields: 1px = 1 second is too coarse.
  Scroll-wheel and direct typing still work with sub-second precision.
- Add mixed-content text-node serialization test in a separate file
  (domEditingTextFields.test.ts) to avoid bloating the existing
  domEditing.test.ts past the filesize limit.

Miguel Ángel 58a370939c fix(studio): fix seek after code edit, improve scrub perf, add click-to-source (#881)
* feat(studio): html-backed motion panel — persist GSAP motion to element attributes

Re-architects the motion panel to store GSAP motion data as a JSON
data attribute (data-hf-studio-motion) on each element instead of a
.hyperframes/studio-motion.json sidecar file. Follows the same
pattern as position/resize/rotation edits: write to DOM, build patches,
persist to HTML source via commitPositionPatchToHtml.

Render pipeline: the studioPositionSeekReapplyRuntime now queries
[data-hf-studio-motion] elements after each seek, parses their JSON,
builds a GSAP timeline, and seeks it to the current frame time.

Studio preview: motion reapply is integrated into the manual edits seek
hook (reapplyPositionEditsAfterSeek). useManifestPersistence is slimmed
to only handle save queue and seek hooks.

* fix(studio): address PR review — html-escape attrs, cache timeline, migrate sidecar, add tests

Blocker: JSON attribute values are now HTML-entity-escaped before being
written into source HTML. Read-back unescapes automatically.

Perf: motion timeline is cached between seeks at render — only rebuilt
when the concatenated JSON key changes, not on every frame.

Migration: on mount, empties legacy .hyperframes/studio-motion.json so
the legacy render script no-ops.

Tests: 46 new tests for motion read/write/clear round-trips, JSON
attribute escaping, and source patcher entity handling.

Nits: removed unused activeCompositionPath param; tightened htmlCompiler
attribute substring check.

* fix(studio): fix seek after code edit, improve scrub performance, add click-to-source

Three issues addressed:

1. **Seek breaks after code edit**: During crossfade refreshes the retiring
   Player's cleanup unconditionally nulled `iframeRef.current`, clobbering the
   reference the new Player had already assigned. Guard the cleanup to only
   clear the ref when it still points to the retiring Player's own iframe.

2. **Scrubber/timeline drag jank**: Every pointermove during a drag called the
   full seek pipeline (adapter.seek + setCurrentTime + React re-render cascade).
   RAF-throttle the expensive onSeek call during drags while keeping slider and
   playhead visuals updated on every pointer event for instant feedback.

3. **Click-to-source**: Clicking an element in the preview now switches to the
   Code tab, opens the element's source file, and scrolls the editor to the
   element's opening tag. Uses the existing `findTagByTarget` source patcher to
   locate the element by id/selector in the HTML source.

* fix(studio): address PR review — gate click-to-source, fix fetch race, guard refs

- Gate click-to-source on Alt/Option+click so it doesn't steal the Code
  tab on every preview click, conflicting with select-to-inspect workflow
- Fix fetch race in openSourceForSelection: AbortController cancels the
  previous in-flight fetch, monotonic request ID prevents stale responses
  from applying the wrong file/offset
- Guard the callback-ref branch in Player cleanup (no-op — can't read
  back from a callback ref to check identity, and the path is unreachable
  today since the ref is always a MutableRefObject)
- Import SidebarTab type instead of duplicating the literal inline

* feat(studio): add Layers panel as new inspector tab

Adds a dedicated Layers tab alongside Design and Renders in the right
panel inspector. The panel shows the full composition element tree with
collapsible hierarchy — clicking a layer selects it without navigating
away from the tree view.

Closes #783

* feat(studio): add visual element previews to Layers panel

Each layer row now shows a small color/content preview thumbnail:
- Text elements show a snippet of their content in the actual font color
- Container elements show their background color as a colored swatch
- Image elements show a tiny thumbnail of the image
- Media elements show an icon indicator

* fix(studio): layers panel tab order, autoseek, and renders toolbar overflow

- Reorder inspector tabs to Design → Layers → Renders
- Fix autoseek: walk DOM ancestors when selected element has no direct

  to the start of its parent scene

* fix(studio): seek to midpoint of element duration in layers panel autoseek

* fix(studio): layers panel seek now drives adapter.seek via requestSeek signal

setCurrentTime() only updated the store — adapter.seek() and liveTime.notify()
were never called so the iframe never moved. Add requestedSeekTime to the player
store; useTimelinePlayer subscribes and calls the real seek() path when it fires.

* feat(studio): hover over a layer auto-seeks to element midpoint (300ms debounce)

* feat(studio): add collapsible sections to Design panel

Section component now supports collapse/expand with a chevron toggle.
Text, Layout, and Fill sections stay expanded by default. Less-used
sections (Flex, Radius, Stroke, Effects, Clip, Transparency) start
collapsed to reduce scrolling.

* fix(studio): remove stale selectedTimelineElement usages dropped in rebase

* fix(studio): stabilize resetErrors in useConsoleErrorCapture to break render loop

resetErrors was a new function object on every render. handlePreviewIframeRef
had it as a dep, so it also changed every render. NLELayout's useEffect watching
onIframeRef would re-fire, calling setPreviewIframe again, which re-ran
useConsoleErrorCapture with the new iframe — infinite loop.

* feat(studio): add persistent undo redo (#537)

Studio manual editing and timeline editing mutate project files directly, but those edits had no reliable undo/redo path. Before releasing manual editing, users need a way to recover from visual property changes, source-editor saves, timeline moves/resizes/deletes, and timeline asset drops.

The history also needs to survive a page refresh. A refresh should not erase the only way back from a bad manual edit.

- Adds a persistent per-project edit-history model for file snapshots.
- Stores undo/redo stacks in IndexedDB so history survives Studio refreshes.
- Records source editor saves, manual DOM edits, and timeline mutations.
- Adds toolbar undo/redo buttons with standard keyboard shortcuts: `Cmd/Ctrl+Z`, `Cmd/Ctrl+Shift+Z`, and `Ctrl+Y`.
- Validates current file hashes before applying undo/redo so external file changes do not silently overwrite newer content.
- Keeps history available in memory if IndexedDB persistence fails during a session.
- Adds focused unit coverage for the pure history model, storage adapter, controller/hook behavior, and project-file save helper.

Studio previously treated every editor mutation as an immediate file write. Manual DOM editing, timeline updates, and source-editor saves each had separate write paths, so there was no common transaction boundary where Studio could capture the file contents before and after an edit.

Undo/redo needed to sit above those write paths as a file-level transaction system: capture changed files before saving, write the new contents, persist the history entry by project, then apply undo/redo only when the current file content still matches the expected snapshot.

* fix: align Studio capture with preview (#595)

Studio frame capture could fail for projects mounted outside the repo when the project id came from an encoded hash route. A project like `Notion Showcase` loaded as `#project/Notion%20Showcase`, but the capture URL encoded that already-encoded value again, producing `/api/projects/Notion%2520Showcase/...` and a 404.

While validating the fix by seeking through the preview, capture also diverged from the visible player for nested compositions because the thumbnail route sought raw timelines instead of the same player seek path used by Studio preview.

- Decodes project ids when reading Studio `#project/...` routes and centralizes project hash/API path construction.
- Keeps API URLs encoded exactly once, including project names with spaces, literal `%`, reserved characters, and unicode.
- Updates Studio thumbnail capture to prefer `window.__player.seek(t)` and only fall back to raw timeline seeking for standalone pages.
- Preserves explicit `t=0` thumbnail requests instead of falling back to `0.5` seconds.
- Adds preview-regression CI coverage for Studio routing, frame capture URL construction, thumbnail seeking, and core thumbnail seek parsing.

Studio treated the hash route segment as the canonical project id even when the browser had already percent-encoded it. `buildFrameCaptureUrl` then encoded that string again, so a decoded project directory name and the capture API path no longer matched.

The preview/capture mismatch was a separate seek-path issue: the visible Studio preview seeks through the HyperFrames player, which maps global time into nested composition time. The capture route bypassed that layer and paused all registered timelines at the same global time.

The zero-second capture case came from parsing `t` with a truthiness fallback, so `parseFloat("0") || 0.5` became `0.5`.

Pre-commit also reran lint, format, and typecheck successfully for the committed files.

Using `agent-browser`, I mounted `/Users/miguel07code/Downloads/Notion Showcase` into Studio's project data and opened:

```text
http://127.0.0.1:5197/#project/Notion%20Showcase
```

Before the fix, Capture requested `/api/projects/Notion%2520Showcase/thumbnail/index.html?...` and Studio showed `Capture failed`.

After the fix, I sought the preview to `0s`, `2s`, `10s`, and `18s`, captured each frame, and compared the visible preview crop against the capture output. The capture URLs all used `Notion%20Showcase`, not `Notion%2520Showcase`, and no failure toast appeared.

Mean pixel diffs for preview vs capture were:

- `0s`: `0.0`
- `2s`: `0.8641`
- `10s`: `0.3496`
- `18s`: `0.2309`

The small non-zero diffs are raster/antialias-level differences after resizing the capture to the preview crop dimensions.

- Browser screenshots, comparison sheets, network logs, and the `agent-browser` recording are local-only under `qa-artifacts/capture-button/` and are not committed.
- The local Notion Showcase project mount is an ignored symlink under `packages/studio/data/projects/` and is not committed.
- Thumbnail cache versions were bumped so stale captures generated with the old seek behavior are not reused.

Fixes and improvements based on power-user testing feedback:

1. Fix stale selection after style edits — handleDomStyleCommit now
   calls refreshDomEditSelectionFromPreview after persisting, matching
   every other commit handler. Without this, the PropertyPanel showed
   frozen computedStyles after color/radius/shadow edits, making it
   look like editing "didn't work." Also adds error handling around
   the persist call.

2. Add rotation field to the Design panel Layout section — reads the
   current rotation angle from the manual edit manifest and commits
   via the existing handleDomRotationCommit handler.

3. Enable motion panel by default — STUDIO_MOTION_PANEL_ENABLED now
   defaults to true so the Motion tab is discoverable without env vars.

4. Color controls only when element has color — fill color section now
   only shows when the element has an explicit non-transparent
   background-color. Text color shows only when the element has a
   color style. Prevents showing color pickers on elements where
   color edits have no visible effect.

5. Exclude canvas from selection — added "canvas" to
   DOM_LAYER_IGNORED_TAGS so canvas elements are not selectable in the
   preview or listed in the layer panel.

6. Multi-selection feedback — shows "N elements selected" with
   guidance instead of the generic empty state when multiple elements
   are selected.

* fix(studio): prevent browser launch timeout from crashing dev server

The shared Puppeteer browser pool in getSharedBrowser() could throw a
30s TimeoutError during launch. This error propagated as an uncaught
rejection and killed the vite process, even though generateThumbnail
had its own try/catch — the browser launch promise rejected outside
that scope. Now getSharedBrowser itself catches launch failures and
returns null, so thumbnails degrade gracefully instead of crashing.

* fix(studio): prevent read-only property crash in manual edit wrappers

The seek/play/applyAfter wrapper functions in manualEdits.ts crashed
with "Cannot set property X which has only a getter" when the player
or timeline objects define seek/play as getter-only properties. This
prevented ALL manual edits (position, rotation, size) from persisting
to disk — the error thrown during applyCurrentStudioManualEditsToPreview
aborted the save queue.

Wrapped all three property assignments in try/catch so wrapping
gracefully degrades when the target object is non-configurable.

Verified: position edit (X=42px) now persists to
.hyperframes/studio-manual-edits.json and survives page refresh.

* fix: alpha preview e2e fixes — exports, init templates, EPIPE crash

Three bugs found via automated e2e testing of the v0.6.0-alpha preview:

1. core: add missing package.json export specifiers for
   studio-api/manual-edits-render-script and
   studio-api/studio-motion-render-script — the alpha.3 npm publish
   failed because the studio build could not resolve these sub-paths.

2. cli: fix init --example creating empty projects — tsup leaves empty
   template directories in dist/ during the build, causing
   existsSync(templateDir) to return true and skip the remote fetch
   fallback. Now checks for index.html inside the dir instead.

3. engine: fix unhandled EPIPE crash in streaming encoder — ffmpeg
   stdin/stdout had no error handlers, so a write after the ffmpeg
   process exits throws an uncaught error that crashes the process.

Verified with 8 consecutive e2e iterations (424 test runs, 0 flaky).

* fix(studio): thumbnail crash, feature defaults, multi-select UX, fps selector

Power-user audit fixes for the alpha studio:

- vite.config.ts: wrap thumbnail generation in try/catch so Puppeteer
  TimeoutError doesn't crash the entire vite dev server as an uncaught
  rejection. Close the page on error to prevent browser session leaks.

- manualEditingAvailability.ts: enable motion panel and manual canvas
  drag editing by default (were both false, undiscoverable without
  knowing the env vars).

- PropertyPanel.tsx: show "N elements selected" feedback when multiple
  elements are selected instead of the generic "Select an element"
  empty state.

- RenderQueue.tsx + App.tsx: add FPS selector (24/30/60) to the render
  export bar instead of hardcoding 30fps. Pass the user's choice
  through to startRender.

* chore: release v0.6.0-alpha.4

* fix(runtime): update clock duration when root timeline is late-bound

Compositions with external sub-compositions (like apple-presentation
with 7 slides) load child compositions via fetch(). The root GSAP
timeline is only bound after all external compositions finish loading,
but the TransportClock duration was only set during initial setup.

When bindRootTimelineIfAvailable runs after the external compositions
load, it captures the root timeline but never updates the clock.
player.getDuration() continues returning 0, so the player's probe
interval never fires the 'ready' event, and the Studio shows "Loading
composition" indefinitely.

Now bindRootTimelineIfAvailable updates clock.setDuration when the
root timeline is late-bound. Guarded with try/catch for the early call
site where clock is not yet initialized (temporal dead zone).

* fix(studio): block element selection while composition is loading

Prevent users from selecting elements in the preview while the
composition is still loading (showing "Loading composition" overlay).
Selection and hover highlighting are suppressed until the player fires
the ready event.

Also reverts motion panel and manual drag editing defaults to false —
these were accidentally set to true during the PR #693 merge.

* chore: release v0.6.0-alpha.5

* chore: release v0.6.0-alpha.6

* fix(runtime): remove per-tick timeline.pause() that causes audio stutter

The seekRuntimeTimeline helper added timeline.pause() before every
totalTime() seek. During transport-driven playback, this runs 60 times
per second, causing GSAP to cascade pause events to media elements on
every frame. The result: audio plays/stops/plays/stops in a stutter
pattern.

The captured root timeline is already paused once in player.play() —
the TransportClock drives it via totalTime(t) which keeps it paused.
The extra per-tick pause() was redundant for the root timeline but
actively harmful for media sync.

Fix: restore the original inline seek for the captured timeline
(totalTime without pause), keep seekRuntimeTimeline with pause() only
for standalone child timelines where explicit pause control is needed.

Also fixes rebase artifact: missing PropertyPanel props in App.tsx.

* chore: release v0.6.0-alpha.8

* fix(runtime): comprehensive audio stutter fix

Three changes that together caused audio play/stop/play/stop stutter
during transport-driven playback:

1. seekRuntimeTimeline called timeline.pause() before every totalTime()
   seek, 60x per second. GSAP cascades pause to media elements on every
   frame. Fix: restore original inline seek for the captured timeline
   (totalTime without pause). The timeline is already paused once in
   player.play(). seekRuntimeTimeline with pause() remains only for
   standalone child timelines.

2. player.play() removed the !tl guard, allowing play without a
   captured timeline. But getSafeTimelineDurationSeconds(null) returns
   0, so the clock has no duration → immediately reaches end → stops →
   restarts. Fix: when no timeline provides duration, fall back to the
   root composition element's data-duration attribute.

3. Audio source attachment added networkState guard that could cause
   the clock to flicker between audio-source and monotonic timing
   on transient media states. Fix: keep !rawEl.error guard (prevents
   errored audio from freezing the clock) but drop the networkState
   check.

* fix(runtime): skip drift corrections on playing video elements

Seeking a playing video resets the browser's decoder pipeline, causing
a ~150ms freeze while it re-buffers. During that freeze the monotonic
clock advances, drift grows, and strict sync fires another seek —
creating a perpetual stutter loop (176 seek events / 8s observed on
the apple-presentation composition).

Skip strict and force drift corrections for playing video elements;
only hard sync (>0.5s catastrophic drift) warrants the decoder-reset
cost. Audio elements are unaffected and retain the full correction
tiers.

Also propagate the asset-loading overlay state to the timeline so
controls are disabled during "Preparing preview assets", matching the
existing behavior for the initial composition loading overlay.

* chore: release v0.6.0-alpha.9

* feat(studio): consolidate keyboard shortcuts into single handler

Move all window-level keyboard shortcuts from 4 separate files into
one `handleAppKeyDown` listener in App.tsx:

- Shift+T: toggle timeline (was App.tsx, separate useMountEffect)
- Cmd/Ctrl+Z: undo (was App.tsx, separate useEffect)
- Cmd/Ctrl+Shift+Z: redo (was App.tsx, separate useEffect)
- Cmd/Ctrl+1: sidebar Compositions tab (was LeftSidebar.tsx)
- Cmd/Ctrl+2: sidebar Assets tab (was LeftSidebar.tsx)
- Delete/Backspace: remove selected element (was Timeline.tsx)

LeftSidebar exposes a ref handle for tab switching. Timeline watches
selectedElement becoming null to clean up popover/range UI state.
History hotkey kept as named function for iframe forwarding.

Playback shortcuts (Space, J/K/L, arrows) and caption nudge remain
in their component hooks — tightly coupled to component state.

* fix(studio): sidebar tab overflow + hot-reload double-refresh

1. Sidebar tabs: use equal 1fr columns, shorter "Comps" label, truncate
   on overflow, tighter padding. Fixes tabs clipping outside the rounded
   pill at narrow sidebar widths.

2. Hot reload: set domEditSaveTimestampRef before every save-then-refresh
   path (source editor, timeline move/resize/delete, asset drop). The
   file-change watcher already checks this timestamp and suppresses
   echoed events — but source editor saves and timeline operations
   weren't setting it, causing a double refreshKey increment that could
   leave the player in a non-playable state.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(studio): delete key removes preview-selected elements

The consolidated keyboard handler only checked selectedElementId
(timeline clips). When a user selected a child element in the
preview via the inspector, selectedElementId was null because
the element didn't correspond to a top-level timeline clip, so
Delete/Backspace did nothing.

Add handleDomEditElementDelete that removes the element referenced
by the current domEditSelection via the remove-element mutation
API. The Delete key handler now falls through from timeline
selection to DOM edit selection.

* fix(studio): remove unused deleteInFlightRef from Timeline

Leftover from moving Delete handling to the consolidated
keyboard handler in App.tsx. Also suppress pre-existing
exhaustive-deps warning on the intentional every-render
selection-change watcher.

* fix(studio): forward all keyboard shortcuts to preview iframe

The consolidated handleAppKeyDown was only added to the parent
window. When focus was inside the preview iframe (after clicking
an element), keydown events didn't reach the parent, so Delete
and other shortcuts didn't fire.

Replace the per-function iframe forwarding (handleTimelineToggleHotkey
only) with the full app-level handler via a ref-stable wrapper.
All app shortcuts (Delete, Undo/Redo, Shift+T, Cmd+1/2) now work
from within the preview iframe.

* fix(core): search inside <template> content when removing elements

linkedom's document.querySelectorAll does not traverse <template>
content. Elements in template-based compositions (like .title-word,
.bullet-text) were invisible to the removal logic, so delete
returned changed: false and the element survived the reload.

Fall back to template.querySelectorAll when the document-level
query returns no matches. Uses template.querySelectorAll directly
(not template.content.querySelectorAll) because removing from
the content DocumentFragment doesn't update the serialized output.

* fix(studio): suppress loading overlay on hot-reload

Only show the composition loading overlay on the first iframe load.
Hot-reloads (source editor save, timeline edits, element delete)
no longer flash the full-screen loading state.

* fix(studio): reorder design panel, fix stroke height, rename Blending

- Move Text section to the top of the panel (before Layout)
- Remove Selection Colors section
- Rename "Blending" to "Transparency"
- Fix stroke Width/Style height mismatch by making SelectField
  use inline label layout matching MetricField

* fix(studio): prevent panel scroll when wheel-adjusting metric inputs

React registers onWheel passively, so preventDefault had no effect
on the parent scroll container. Replace with a native wheel listener
(passive: false) that blocks both default scroll and propagation.

* chore: release v0.6.0-alpha.12

* fix(studio,player,core): eliminate double audio and manifest polling loop (#722)

Three bugs that compound in Studio preview:

1. **Double audio on pause/resume**: syncRuntimeMedia played audio through
   the HTML <audio> element while WebAudioTransport simultaneously played
   the same source through AudioBufferSourceNode. Fixed by passing
   webAudio.isActive() as outputMuted so HTML elements stay muted when
   Web Audio owns playback. Also removed the priorMuted restore in
   stopAll() which raced with the next play cycle.

2. **Manifest polling loop**: applyStudioManualEditsToPreview and
   applyStudioMotionToPreview unconditionally fetched from disk on every
   call, even without forceFromDisk. The runtime posts state messages
   every frame via postMessage, triggering React re-renders that re-invoked
   these functions ~60x/second. Fixed by returning early when no disk read
   is requested, and using refs instead of callbacks in useEffect deps.

3. **Parent proxy double-play**: the player web component created parent-frame
   audio proxies even when the runtime bridge was available, causing two
   audio sources on autoplay-blocked promotion. Fixed by skipping proxy
   creation when _hasRuntimeBridge returns true, and synchronously muting
   iframe media on promotion to close the async race window.

Also fixes pre-existing ResolutionPreset type missing square variants.

* fix(studio): improve font picker and text property controls (#736)

- Line height and letter-spacing: convert from free-text to select with presets
- Font style: remove oblique (browser falls back to italic), keep normal/italic
- Font weight: detect available weights via document.fonts.check(), add labels
- Font source: local fonts matching Google catalog tagged as Google
- Font list: balanced per-source caps prevent any source from being cut off
- Sort order: Google fonts rank before Local so curated fonts appear first

* fix(studio): inspector visibility, undo/redo blinking, and preview caching

Inspector picks invisible elements when an ancestor has GSAP-set opacity: 0
because CSS opacity is not inherited — getComputedStyle on the child still
returns 1. Walk the ancestor chain in the picker, domEditing, and overlay
visibility checks to catch this.

Also:
- Containers with all-invisible children are no longer selectable
- Selection/hover overlay hides during playback and while loading
- Undo/redo no longer double-refreshes (echo suppression for all file writes)
- Undo/redo reloads iframe in-place instead of recreating the Player,
  preserving shader transition cache
- Preview routes return ETag + Cache-Control headers; composition HTML uses
  project signature for conditional 304, binary assets use mtime+size
- Loading overlay deferred 400ms so cached loads never flash it

* fix(studio): remove timeline inspector buttons, enable manual dragging

Remove the eye icon (inspector) and image icon (thumbnail toggle) from timeline
clips. The timeline layer inspector feature and all supporting code is removed.

Enable manual dragging in the preview by default. Add scrub-to-drag on X/Y/W/H
fields in the design panel. Hide the Radius section when the element has no
visible background. Fix pre-existing ResolutionPreset type for square presets.

* chore: release v0.6.0-alpha.13

* fix(studio): add rotation field, inline element drag, fix manifest load regression (#743)

- Add rotation (R) field to geometry row (X, Y, W, H, R) in property panel.
  Goes through manifest via handleDomRotationCommit, resettable with Reset Edits.
- Auto-promote display:inline elements to inline-block when dragged so
  translate works on inline spans.
- Fix regression from polling fix: iframe load now passes readFromDiskFirst
  to load manifest from disk, so Reset Edits finds existing entries.

* refactor(studio): decompose App.tsx monolith (4297 → 567 lines) (#741)

* refactor(studio): decompose App.tsx from 4297 to 567 lines

Break the monolithic StudioApp component into focused modules:

Hooks (12 new):
- usePanelLayout: resizable/collapsible panel state
- useFileManager: file tree, CRUD, uploads, derived lists
- useManifestPersistence: manual edit + motion manifest save queue
- useTimelineEditing: clip move/resize/delete/drop handlers
- useDomEditSession: DOM selection, style/text commits, preview interaction
- useAppHotkeys: keyboard shortcuts, undo/redo, iframe hotkey sync
- useCaptionDetection: auto-detect caption compositions
- useRenderClipContent: timeline clip thumbnail rendering
- useConsoleErrorCapture: preview iframe console error capture
- useFrameCapture: frame capture download flow
- useLintModal: lint execution and modal state
- useCompositionDimensions: stage-size message listener

Components (6 new):
- AskAgentModal: agent prompt modal
- StudioHeader: toolbar with undo/redo, capture, inspector toggle
- StudioLeftSidebar: file tree + code editor (handles collapsed state)
- StudioPreviewArea: NLELayout + overlays + caption timeline
- StudioRightPanel: Design/Motion/Renders tab panel
- TimelineToolbar: zoom controls + timeline toggle

Utilities (4 new):
- studioHelpers: types, path helpers, DOM utilities
- studioPreviewHelpers: preview pointer/player interaction
- domEditHelpers: selection group algebra
- studioFontHelpers: font injection + @font-face management

Also removes dead timeline layer inspector code (eye icon, thumbnail
toggle, layer panel) that was disabled behind a feature flag.

* feat(studio): add Layer (z-index) field to design panel

Adds a scrub-enabled "Layer" field below the W/H inputs in the Layout
section. Available for all elements regardless of style editing
capability since z-index is fundamental to composition stacking order.

* docs: architecture spec for studio domain contexts, hook split, and file-size lint

* docs: implementation plan for studio contexts, hook split, and file-size lint

* refactor(studio): consolidate duplicate helpers in useDomEditSession

Remove ~370 lines of helper functions that were copied into the hook
instead of imported. All removed functions already exist in the
canonical utility files (studioHelpers, studioFontHelpers,
studioPreviewHelpers, domEditHelpers). Also removes the duplicate
local type definitions for RightPanelTab, AgentModalAnchorPoint, and
PreviewLocalPointer, and drops now-unused imports (googleFontStylesheetUrl,
importedFontFaceCss, resolveVisualDomEditSelectionTarget, DomEditViewport).

Temporarily excludes useDomEditSession.ts from the 500 LOC file-size
check until Tasks 3-5 split it into focused hooks.

* refactor(studio): extract useDomSelection from useDomEditSession

* refactor(studio): extract useAskAgentModal from useDomEditSession

* refactor(studio): extract usePreviewInteraction from useDomEditSession

* refactor(studio): extract useDomEditCommits, useDomEditSession now thin orchestrator

Split the 897-line useDomEditSession into focused hooks:
- useDomEditCommits (439 LOC): manifest commits (path offset, box size,
  rotation, manual edits reset, motion), persist operations, element delete,
  font asset resolution
- useDomEditTextCommits (329 LOC): style/text/text-field commits
- useDomEditSession (339 LOC): thin orchestrator wiring selection, agent
  modal, preview interaction, and commit hooks

All files now under 500 LOC limit. Removed the temporary lefthook
filesize exclusion for useDomEditSession.

* feat(studio): add 4 domain contexts (PanelLayout, FileManager, DomEdit, Studio)

Create context providers that wrap hook return values for prop-drilling
elimination. Each context destructures and reconstructs the value inside
useMemo so exhaustive-deps is satisfied and re-renders are minimized.

Not yet wired into App.tsx — that comes in a follow-up.

* refactor(studio): wire domain contexts, eliminate prop drilling in 4 components

Wire StudioProvider, PanelLayoutProvider, FileManagerProvider, and
DomEditProvider in App.tsx. Migrate StudioHeader, StudioLeftSidebar,
StudioPreviewArea, and StudioRightPanel to consume contexts instead
of props.

Prop counts reduced:
- StudioHeader: 13 -> 6
- StudioLeftSidebar: 19 -> 4
- StudioPreviewArea: 37 -> 11
- StudioRightPanel: 39 -> 3

Net: -118 lines, 108 props removed from call sites.

* chore: upgrade to React 19

Upgrade react and react-dom from 18.3 to 19.2.6 across the workspace.
Add resolutions/overrides in root package.json to prevent peer
dependency pins (e.g. @phosphor-icons/react) from pulling React 18.
Regenerate bun.lock.

This enables the React 19 context syntax (<Context value={...}>)
used by the new domain contexts.

* fix(studio): refresh preview after z-index change so stacking updates visually

* fix(studio): remove duplicate duration override causing oscillation

The timeline message handler set the duration twice: once via
processTimelineMessage and once via a raw durationInFrames override.
When drilled into a sub-composition, these could disagree, causing
the duration to oscillate after element deletion.

* fix(studio): use in-place iframe reload after clip delete, remove confirm dialogs

Two changes to fix duration oscillation after deleting a timeline clip:

1. Replace setRefreshKey (full Player remount) with in-place
   iframe.contentWindow.location.reload() after deleting a clip.
   The full remount triggered a chaotic re-probing cycle with multiple
   duration sources (adapter, manifest, postMessage) fighting each
   other, causing the timeline to oscillate between durations.
   In-place reload preserves the Player web component and its state.

2. Remove window.confirm dialogs from both timeline clip delete and
   DOM element delete. Undo is available so the confirmation adds
   friction without value.

* chore: gitignore docs/superpowers

* feat(studio): add favicon

* perf(studio): skip no-op state updates in timeline sync

syncTimelineElements was called 60+ times per page load, each time
triggering setElements/setDuration/setTimelineReady even when nothing
changed. This caused massive re-render churn and memory usage.

Add early-return guards to skip updates when values haven't changed.
Also fixes the duration oscillation after element delete.

* refactor(studio): split PropertyPanel.tsx (3126 LOC) into 8 focused modules

The monolithic PropertyPanel.tsx exceeded the 500 LOC filesize limit.
Split into cohesive modules by responsibility:

- propertyPanelHelpers.ts (401) — pure utility functions, shared types/constants
- propertyPanelPrimitives.tsx (357) — CommitField, MetricField, DetailField,
  SliderControl, SegmentedControl, SelectField, Section
- propertyPanelColor.tsx (371) — ColorField, ColorSlider
- propertyPanelFill.tsx (421) — ImageFillField, GradientField, asset path helpers
- propertyPanelFont.tsx (455) — FontFamilyField + font catalog helpers
- propertyPanelSections.tsx (453) — TextSection, TextFieldEditor, text controls
- propertyPanelStyleSections.tsx (411) — StyleSections (stroke, effects, clip, fill)
- PropertyPanel.tsx (347) — main component, LayerTree, re-exports for consumers

All re-exports from PropertyPanel.tsx preserved for backwards compatibility.
No behavioral changes — pure structural split.

* fix(studio): use in-place iframe reload for all timeline operations

Replace setRefreshKey with in-place iframe reload for move, resize,
and asset drop — matching delete which was already fixed. Prevents
the Player remount probe cycle that causes duration oscillation.

* perf(studio): replace 5s polling loop with event-driven adapter init

The Player's onIframeLoad used a setInterval polling loop (25 attempts
× 200ms = 5 seconds) to detect when the runtime's __player/__timeline
globals appeared. Each poll that missed triggered wasted work, and
multiple duration sources fighting during the probe cycle caused
oscillation bugs.

Replace with event-driven initialization:
1. Fast path: try initializeAdapter() immediately (works for in-place
   reloads where the adapter is already present)
2. If not ready, listen for the runtime's "state"/"timeline" postMessage
   signals and initialize on the first one
3. Single 5s timeout as safety net (replaces 25 interval ticks)

This eliminates the polling overhead, reduces setDuration/setElements
calls to exactly 1 per load, and makes the Player responsive within
one frame of the runtime being ready instead of up to 200ms later.

* fix(studio): prevent duration oscillation after element delete

Two fixes for the duration display oscillating between sub-composition
and master durations after deleting an element in the preview:

1. Clear store elements before iframe reload in handleDomEditElementDelete.
   Without this, stale pre-delete elements remain in the store and cause
   mergeTimelineElementsPreservingDowngrades to alternate between REPLACE
   and PRESERVE modes as the element count fluctuates.

2. Add 500ms cooldown on enrichMissingCompositions after timeline messages.
   The "state" handler was calling enrichMissingCompositions every ~80ms,
   which added extra elements from GSAP timelines. These fought with the
   authoritative element list from "timeline" messages (~333ms), creating
   a feedback loop where element count oscillated and triggered alternating
   merge strategies with different durations.

* fix(studio): single reloadPreview as source of truth for preview refresh

Create reloadPreview() in App.tsx that encapsulates the correct
behavior (in-place iframe reload with setRefreshKey fallback). Pass it
as the sole refresh mechanism to hooks, removing direct setRefreshKey
access from useTimelineEditing and useDomEditCommits.
