Miguel Ángelandukimsanov df29fa7a5e feat(studio): revamps Studio + improves code quality (#2291)
* feat(studio): glue API coexistence layer for the NLE swap

What: extends 21 glue files so the OLD timeline/canvas engine and the NEW
NLE components type-check side by side: playerStore (multi-select setters,
zoom pin, snap toggle, non-reactive scale scratch), drag-state types gain
optional NLE fields, timelineLayout/timelineAssetDrop/timelineEditingHelpers/
timelineEditing/timelineElementHelpers/studioHelpers/assetHelpers gain the
NLE exports, DomEditOverlay + gestures + AssetContextMenu + Timeline props
gain optional callbacks/params, contexts gain *Optional hooks, and
TimelineEditCallbacks.onMoveElements becomes a bivariant method accepting
both engines' change shapes. patchDocumentRootDuration's test rides along.

Why: this is the keystone that dissolves the old "welded glue" problem —
every symbol the NLE components need is ADDED next to what the old engine
still uses, so the engine components and the swaps can land as separate
reviewable PRs.

How: 15 authored intermediate files (main content + additive symbols; no
behavior changes — new fields optional, new callbacks unused until wired)
plus 6 files whose final content is already purely additive. New exports
without consumers yet carry TEMP(studio-dnd) ignoreExports entries, removed
by the app-shell swap.

Test plan: tsc --noEmit in studio + studio-server (verifies BOTH engines
compile); bunx vitest run (full suite green incl. the 6 new
patchDocumentRootDuration tests); fallow audit clean.

* feat(studio): timeline interaction hooks and lanes component (unwired)

What: the timeline-side wiring layer, unwired: TimelineLanes (the lane
renderer driving drag/resize/marquee), timelineMarquee (+tests),
useTimelineStackingSync, useTimelineGeometry, useTimelineEditPinning,
useTimelineEditingDrops.

Why: everything between the pure drag math and <Timeline> itself; the
timeline-glue swap PR then only rewires Timeline/TimelineCanvas onto these.

How: new files, tsc-clean against the coexistence layer. Unwired components
carry TEMP(studio-dnd) entry registrations, removed at the app-shell swap.

Test plan: bunx vitest run timelineMarquee.test.ts; tsc --noEmit; fallow
audit clean.

* feat(studio): NLE shell assembly (unwired)

What: EditorShell (the full editor layout replacing NLELayout +
StudioPreviewArea), TimelinePane (timeline host with sub-comp rebasing) and
useTimelineEditCallbacks (the callback bag bridging store edits to the
timeline), all unwired.

Why: the shell that App swaps to in the final step; reviewing it standalone
keeps that swap PR small.

How: new files against the coexistence layer; TEMP(studio-dnd) entries
until App mounts EditorShell in the app-shell swap.

Test plan: tsc --noEmit; bunx vitest run (suite unchanged); fallow audit
clean.

* feat(studio): timeline glue swap — Timeline/TimelineCanvas onto the NLE engine

What: flips the timeline glue to its final form (23 files): Timeline and
TimelineCanvas rebuilt on TimelineLanes/TimelineOverlays, useTimelineClipDrag
drives preview/commit through the new drag engine, range selection goes
multi-select, playback loop moves to useTimelinePlayerLoop. Deletes the 9
old-engine files this orphans (group drag, marquee selection, snap targets,
layer gutter, selection overlays + their suites) — each is compile- or
gate-forced by this swap, verified by probe.

Why: second swap step; timeline-only, canvas and App untouched.

How: modified files to final content + forced deletions.
playerStore/timelineEditing/timelineCallbacks stay at their coexistence
form until the app swap (the old App still runs on them).

Test plan: tsc --noEmit; bunx vitest run (full suite); fallow audit clean.

* feat(studio): clip thumbnail modules

What: ImageThumbnail (+tests) and thumbnailUtils (+tests) — frame decode
with SVG/AVIF format fallbacks and rounded-corner clipping — plus
VideoThumbnail updates.

Why: the decode layer for timeline clip thumbnails, ahead of the visual
refresh that renders them.

How: new modules + one modified file; purely presentational.

Test plan: bunx vitest run on both test files; tsc --noEmit; fallow audit
clean.

* feat(studio): assets/blocks panel behaviors + preview helpers

What: blocks tab install flow, right-panel and global drag-overlay polish,
music beat analysis and clip-content rendering hooks, and the
preview-helper utilities backing asset preview.

Why: completes the studio NLE stack on top of the visual refresh.

How: modified files only (kept as one PR: splitting further would produce
sub-150-LOC fragments of interdependent panel glue).

Test plan: bunx vitest run studioPreviewHelpers/studioUrlState suites; tsc
--noEmit; fallow audit clean.

* fix(studio): preserve graded resize and crop geometry

* fix(studio): log resize/rotate commit failures, move anchor accumulator to resize-local

* fix(studio): treat duration-0 tweens as static holds and settle resize position before persist

Instant holds (to()/fromTo() with duration 0) were classified as animated
tweens by every commit route, so resizing or rotating them converted the
hold into a corrupt duration-0 keyframes tween (new value at 0%, old at
100%) that GSAP drops; panel edits appended a losing set. A shared
isInstantHold() now routes them through the static replace-in-place path,
and percentage math guards zero-duration windows.

Separately, anchored-corner resizes painted 3-5 frames at the new size but
old position while the offset persist round-tripped the server. The commit
path now applies the corrected GSAP position synchronously before awaiting
the offset persist, mirroring the scale route's settle.

* feat(studio): gesture-transaction seam with commit observability

Introduce runGestureTransaction — one owner for a gesture commit's
settle -> persist -> record lifecycle. It settles the live DOM
synchronously before any async persist, folds every mutation into one
undo entry via a per-transaction coalesceKey, restores pre-gesture state
exactly once on failure, and asserts (dev console) + reports (PostHog:
commit_transaction / commit_invariant_violation / commit_transaction_failed)
that a persist never changes pixels. The box-size resize path is migrated
onto it; the ad hoc per-route coalesceKey/reload handling is removed.

Extract the resize draft-rect math into resizeDraft.ts to keep the
gesture-handler file under the size cap.

Also: keep url_hash telemetry to the route slug only (drop the query
string, which carried the user's selected element id/selector), and gate
the [hf-resize] diagnostics behind localStorage hf-resize-debug so they
ship as opt-in tracing rather than console noise.

* fix(studio): transaction owns the undo label

The coalesced history entry took the last sub-mutation's label, so a
resize surfaced as "Move layer" (the offset persist) in undo/redo. The
seam now stamps tx.label on every wrapped mutation, so the folded entry
reads as the gesture.

* fix(studio): atomic static size/position commits (no data loss)

Static resize/position holds updated an existing set via delete+add — two
undo entries, and a delete that succeeded before a failed add lost the
hold on disk. Use one in-place update-properties mutation when a set
exists (one undo entry, no partial-failure window). The keyframed-hold
heal that can't be expressed as a property update now adds before it
deletes, so any single failure leaves a recoverable duplicate, never a
lost hold. Transaction-owned commits are tracked via a WeakSet so the
heal path never double-wraps an already-wrapped gesture.

* fix(core): restore timed-clip visibility after a forced timeline rebind

__hfForceTimelineRebind force-rendered the re-registered timeline but never
re-ran the per-[data-start] visibility pass, so after undo or soft reload
every clip rendered regardless of its time window until a full page reload.
Extract the visibility loop into syncTimedElementVisibility and call it from
both syncMediaForCurrentState (unchanged) and the rebind.

* fix(studio): atomic z-order/keyframe/split commits, one undo entry each

Three edit-commit paths hardened onto the one-transaction invariant:

- Z-order reorder (useElementLifecycleOps): N per-element writes now fold
  into one undo entry (coalesceMs Infinity) and, on a failed persist,
  restore already-written files to disk so no partial reorder survives.
- Enable-keyframes (useEnableKeyframes/useGsapKeyframeOps): the intermediate
  convert phase no longer full-reloads the preview (skipReload), killing the
  black-flash remount; convert + edit share one coalesce key = one undo entry.
- Razor split-all (useRazorSplit): snapshot before the batch and restore on
  any failure, so a mid-batch error never leaves un-revertable partial splits.

Shared file-history helpers (RecordEditInput, DomEditCommitBaseParams,
readProjectFileContent, restoreFilesToOriginal) dedupe the rollback/commit
logic across these paths. Commit options thread as one partial object rather
than field-by-field. Test setup extracted into colocated helpers.

* fix(studio): fold multi-step edits into one undo entry; guard text revert

- Gesture recording (useGestureCommit): the per-property-group commits now
  share one coalesce key and only the last reloads, so a recording is one
  undo entry and one preview reload instead of up to four.
- Delete selected keyframes (deleteSelectedKeyframes, split out of
  timelineEditingHelpers): N removals fold into one coalesced undo entry
  with a single reload.
- Text-field commit (useDomEditTextCommits): commitDomTextFields now uses
  the same version-guarded revert as handleDomTextCommit, so a stale failed
  commit can no longer stomp a newer successful one.

* feat(studio): batch a gesture's mutations into one atomic server write

A transaction that emits N mutations previously did N sequential POSTs,
each rewriting the file and soft-reloading — the root of the multi-phase
persist window. Add a gsap-mutations-batch endpoint that validates every
mutation up front, applies them in one in-memory rewrite chain, and writes
the file once (all-or-nothing: an invalid entry rejects the whole batch,
no partial write). The seam buffers a transaction's commits and, when more
than one targets the same file, dispatches a single batch — one write, one
history entry, one reload. The batch capability rides on the existing
commit-function reference; no option fields are threaded through callers.

* fix(studio): soften off-canvas indicator outline to 30% opacity

The dashed off-canvas selection outline at 60% was noisy with many
protruding elements on screen; drop the resting opacity to 30% (hover
still restores full opacity so it stays discoverable).

* fix(studio): drop off-canvas indicator outline to 10% opacity

Follow-up to the 30% softening — 10% resting opacity reads much calmer
with many protruding elements; hover still restores full opacity.

* fix(studio): gate [hf-commit] console traces to dev only

The start/settled/persisted/restore lifecycle traces logged on every
gesture commit in all environments — console noise for end users. Route
them through a dev-only traceCommit helper (matching the pixel-violation
error's existing DEV gate). The commit_* PostHog events stay always on;
they are the production observability, the console lines are a dev aid.

* fix(studio): count actual reloads, not softReload requests, in commit telemetry

A resize's size and offset persists both request softReload; the seam
counted each request, so a batched gesture reported reload_count 2 even
though the batch is one write and one reload. Compute the count from what
dispatchBufferedCommits actually did — one for a batch, the request count
for the sequential fallback.

* fix(studio): rotate hover + off-canvas overlays with the element; flicker-free crop

- Hover overlay applied the element's rotation only to the selection chrome,
  not the hover box; it now rotates about center like the selection, via a
  shared orientedGroupAwareOverlayRect router (one owner for rotation-aware
  overlay geometry across hover/selection/off-canvas).
- Off-canvas indicator was axis-aligned; it now rotates with the element and
  inverse-rotates the canvas-exclusion clip into the element's local frame,
  so the protruding-sliver clip stays correct for rotated elements.
- Crop commit re-lifted the element only in the commit's .then(), so one
  frame painted the cropped state (the flicker). Re-lift synchronously right
  after onStyleCommit (which applies the clip before its first await), so the
  cropped state never paints; the persisted file value is unchanged.

* fix(studio): address code-review findings across the commit-hardening campaign

Correctness (would ship green, bite under latency):
- Enable-keyframes phase 2 now carries coalesceMs: Infinity, so the convert
  folds into one undo entry instead of splitting past the 300ms default.
- The SDK keyframe persist path forwards coalesceMs (CutoverOptions gains the
  field); multi-keyframe delete and convert coalesce correctly when SDK-routed.
- Razor split-all's rollback is guarded so a failing restore can't swallow the
  error toast that tells the user the split failed.

Simplification (single source of truth / no dead flexibility):
- Decompose resolveResizeDraftRect (drops a fallow-ignore suppression).
- Delegate the third readProjectFileContent copy to the shared helper.
- Inline setPatchFromUpdateProperties (its only caller passes one mutation).
- One toSdkPersistOptions translates gesture overrides to SDK options.
- Bundle the reorder-rollback deps into one object (was 7-9 positional args).
- Dedupe the 'last group reloads' ternary; type gesture options as
  CommitMutationOptions; drop a Map+array wrapper around a single write.

* feat(studio): atomic z-order reorder via batch patch-element endpoint

Z-order reorder issued N per-element inline-style patches (one server
write each), so a mid-chain failure could leave a partial reorder on disk.
Add a patch-elements-batch endpoint that validates every patch, folds them
over the file in one in-memory rewrite, and writes once (all-or-nothing;
unsafe input rejects with no write). The reorder now sends one batch per
source file and records one undo entry. Because a failed atomic write
persists nothing, the interim disk-write-back rollback (restoreReorderedFile
/ restoreFulfilledReorderFiles / ReorderRollbackDeps) is deleted — failure
rolls back only live DOM/store state. Closes the last disk-atomicity gap.

* fix(studio): razor-split undo no longer silently no-ops

The split clone was written to disk without a data-hf-id, so the split
endpoint recorded that unstamped HTML as the undo entry's afterHash. The
next reloadPreview() ran the preview route's ensureHfIds write-back, which
minted a fresh id and persisted DIFFERENT bytes — so at undo time the disk
hash no longer matched afterHash and editHistory's content-mismatch guard
silently refused the undo (no write, no network, no error). Stamp the split
output via ensureHfIds in splitElementInHtml before it is written/returned,
so the preview write-back is a no-op and the recorded afterHash always
equals the final on-disk bytes. Fixes at the source rather than relaxing the
mismatch guard. Corrects the stale comment that credited forceReloadSdkSession.

* feat(studio): closed-hand grab cursor on the rotate handle

The rotate handle used the default arrow cursor; show a grabbing
(closed-hand) cursor on hover to signal it's grabbed and dragged to rotate.

* fix(studio): dropping a dragged element over another no longer selects it

A moved drag's release fired the box click, which re-selected whatever now
sat under the pointer via the hover cache — so dropping an element over a
higher-z one selected the drop target instead of keeping the dragged
element selected. The drag-move branch now suppresses the next box click,
mirroring the resize branch.

* fix(studio): group drag is one undo entry, not one per element

Dragging a multi-selected group committed each member's position write as
its own undo entry, so reverting took N Cmd+Z presses. Force a shared
coalesceKey (infinite window) across every member's commit so they fold
into a single undo entry, like the other multi-step commit paths.

* fix(studio): undo of a split no longer leaves a ghost clip in the timeline

The file and the composition iframe revert correctly on undo, but the
timeline panel kept a ghost node for the split clone. The element-merge
that repopulates the timeline preserves elements the fresh scan dropped —
intended for enriched sub-composition children a bare DOM re-scan misses,
but it also preserved a genuinely-removed TOP-LEVEL element (the split
clone after undo), leaving a phantom clip. Restrict the preserve to
elements with a compositionSrc (the enriched sub-comp children); a
top-level element missing from the fresh scan was truly removed.

JamesandClaude Fable 5 267b289bb8 feat(studio): bind selected element properties to variables
Ninth PR of the template-variables stack: the promote-a-property gesture.
Select an element on the canvas/timeline, open the Variables tab, and the
panel offers per-property bind actions.

- "Bind selected" card in the Variables panel, built from the selection:
  image/media source (img/video/audio), text, text color, background, and
  font. Each action declares a variable whose default is the element's
  CURRENT value (promoting never changes the render — computed rgb colors
  convert to hex, the first computed font family becomes the font default)
  and writes the declarative binding the runtime resolves: data-var-src /
  data-var-text attributes or `<prop>: var(--id)` styles. Declare + bind
  run as one batched schema edit (one undo step); binding to an
  already-declared id skips the declare and just binds.
- guarded to selections from the composition the session models — a
  selection in another source file never writes bindings into this one.
- core: extract readVariablesForElement into runtime/variableScope.ts,
  shared by color grading and the declarative bindings (was duplicated).
- fix(studio-server): buildSubCompositionHtml's extractElementAttrs
  rebuilt html/body attributes without HTML-escaping values, shredding
  quote-bearing attributes — data-composition-variables (a JSON array)
  came out as mangled bogus attributes, so getVariables() silently
  returned {} on every /preview/comp/* page (no declared defaults, no
  runtime bindings). Pre-existing bug surfaced by live-testing this
  feature; regression test added.

Verified end-to-end in a live session: select headline → Bind text color
→ declaration + var(--headline-color) written to disk → override in the
panel → runtime applies the custom prop and the element renders the
override.

JamesandClaude Fable 5 2e0b884521 feat(studio-server): preview variable injection + render variables forwarding
Fourth PR of the template-variables Studio stack — the HTTP plumbing.

- preview routes (/preview and /preview/comp/*) accept
  ?variables=<url-encoded json> and inject
  `window.__hfVariables = {...}` into <head>, before the runtime and any
  composition script — the exact global the engine sets via
  evaluateOnNewDocument at render time, so preview-with-values cannot
  diverge from render output. Values are escaped against </script>
  breakout, malformed payloads 400 instead of silently previewing
  defaults, and the ETag is salted with a hash of the payload so cached
  previews revalidate when values change.
- POST /projects/:id/render accepts variables ({variableId: value}) and
  forwards them through StudioApiAdapter.startRender into the producer's
  RenderConfig.variables — the same channel `hyperframes render
  --variables` uses. Wired in both adapters (CLI embedded server + vite
  dev adapter).

Vance Ingalls e4c4d2e15d fix(studio-server): address PR #2097 review feedback on relative-timing resolver
Documents the shared-pattern context (3rd copy of "resolve relative
data-start", after runtime startResolver.ts and the SDK's own
getElementTimings) and explains when the raw parseFloat fallback in
resolveStart's else branch can actually fire (a malformed grammar string
with a leading number). Adds a test pinning the "reference target exists
but its own timing is unresolvable" branch, which existing tests didn't
cover (only "target doesn't exist" was tested).

Cross-checked the negative-offset clamp concern raised in review: the
SDK's own resolveReferenceStart (session.ts) also clamps to
Math.max(0, ...), so this stays consistent with its sibling — no code
change needed there.
2026-07-09 11:27:53 -07:00
Vance Ingalls fbd21d5709 fix(studio-server): previewAdapter getElementTimings ignores relative data-start refs
Same bug class as the SDK's getElementTimings fix (#2092): data-start can be a
relative-reference expression ("intro", "intro + 2"), not just an absolute
number. The old code did a raw parseFloat on it, so any reference silently
resolved to undefined instead of an actual time.

Also: this function never read data-duration at all (only data-start/data-end
literally), so a reference to a duration-authored (not end-authored) clip was
unresolvable regardless of the parseFloat bug — resolving a reference needs
the target's END, which for a duration-authored clip requires start+duration.

Both fixed together via the shared parseStartExpression grammar parser
(@hyperframes/core/runtime/start-expression), with the same cycle-guard
pattern as the SDK fix. Reference resolution against other elements is scoped
to this file's existing findById (bare data-hf-id lookup).

6 new tests: duration-based end resolution, relative reference (with and
without offset), missing target, and a mutual-cycle termination check.

Miguel Angel Simon Sierra 9f6c20e482 perf(studio): grow composition duration live on extend, no preview remount
Extending a clip past the video end used to force the server-fallback
path that fully remounts the preview iframe (the SDK fast path can't
express the root composition's data-duration, and the runtime bakes+drops
data-duration at load so it can't be patched live). On a large comp that
remount is a visible hitch.

Add a runtime control-bridge action set-root-duration -> clock.setDuration,
so the studio can grow the transport length in place. On an extend the
studio now posts it (and patches the clip's own timing live) instead of
reloading; it only reloads when a GSAP source rewrite actually happened
(the gsap-mutation endpoints now report a mutated flag). Non-animated
extends — the common case — commit as fast as a normal edit.

Verified: bridge dispatch + studio no-reload/post-message paths unit-
tested; core/studio/studio-server typecheck + suites green; the built
runtime artifact carries the handler; E2E confirms the extend no longer
remounts the preview and still persists.

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.

Vance IngallsandClaude Fable 5 3a717fa719 fix(parsers,sdk,studio-server,studio): unify hf-id space across preview, disk, and SDK session (#1981)
* fix(parsers,sdk,studio-server,studio): unify hf-id space across preview, disk, and SDK session

Root-causes the setTiming element_not_found resolver-shadow divergence class:
timeline edits carry hf-ids read from the live preview DOM, but the preview
minted ids AFTER rewriting attributes (and never persisted them for sub-comps),
while the SDK session mints from the raw file — content-keyed minting then
yields different ids for the same element. Template-based comps were worse:
the SDK excluded the whole <template> subtree, so the session had zero
elements and every edit diverged.

- parsers: ensureHfIds now descends into <template> subtrees (linkedom's
  querySelectorAll does not), minting and pinning inner ids
- sdk: buildRoots/buildElement treat <template> as a transparent container,
  and resolution (resolveScoped, animation-id map) searches template subtrees
  via querySelectorAllDeep — template comps now model, resolve, and edit
- studio-server: the sub-comp preview route persists hf-ids to the raw file
  BEFORE the rewrite pipeline (mirrors the main route), pinning one id space
  across served DOM, disk, and SDK session
- studio: resolver-shadow skips structurally-empty sessions (no event, no
  attempt) and tags fail-open emissions with sourceReadFailed so read errors
  are distinguishable from unwired readers in telemetry

* fix(parsers,sdk,studio-server,studio): scope template descent, guard persist route

Addresses the 10 verified findings from the PR #1981 review:

- Restrict template transparency to COMPOSITION templates
  (<template data-composition-id>) everywhere — ensureHfIds, SDK
  buildChildren, querySelectorAllDeep. A plain <template> (runtime
  clone-source) keeps its old fully-excluded behavior: stamping its
  interior would duplicate one persisted id across every runtime clone,
  and modeling it would show phantom timeline clips.
- Guard the sub-comp persist: only .html files (the wildcard route can
  serve any project path — stamping an SVG corrupted it on disk),
  try/catch the read (file-removed race becomes 404, not 500), salt the
  etag (v2) so pre-fix cached clients don't 304 past the id pin, and
  thread the stamped content into buildSubCompositionHtml so served ids
  match the mint even when the disk write is skipped.
- Rewrite querySelectorAllDeep as a document-order DOM walk — appending
  template matches after top-level matches made duplicate-id tiebreaks
  disagree with the preview's unwrapped DOM (wrong-element edits).
- Recurse sourceMutation.querySelectorAllWithTemplates so server-side
  ops resolve ids at any template depth, matching SDK resolution.
- Replace the empty-session silent skip with ONE tagged session_empty
  event per session — silence would blind the tripwire to exactly the
  modeling-gap class that exposed the template bug. Attempts stay
  uncounted (an unmodelable comp can't cut over).

* fix(studio-server): close TOCTOU in sub-comp hf-id persist (CodeQL js/file-system-race)

Replace the route-level stat/read/persist sequence with stampFileHfIds:
validation (fstat), read, mint, and write-back all go through ONE open
file descriptor (O_NOFOLLOW where supported), so the path cannot be
swapped between validation and write. Falls back to read-only stamping
when the file isn't writable — content-keyed minting means the SDK
derives the same ids from the same bytes even without the disk write.

  blocked-drag, plain overlay click) instead of just the overlay path
- pointer-events override detection reads computed style, not inline style,
  so a CSS-class opt-in (not just inline style=) on a descendant is honored
- defensively remove the pointer-events override before the group-fallback
  check too, closing a theoretical gap in the no-elementsFromPoint branch
- a click that resolves to nothing (dead-zone / deselect) no longer leaves
  playback paused if it was already playing

* fix(studio-server): child-scoped patch operations with batch abort

- PatchOperation gains optional childSelector/childIndex resolved under the matched parent
- pre-pass resolves every op target; any miss aborts the batch with matched:false, no partial write
- style-decl parsing extracted to sourceStyleMutation to stay under the file-size cap
- new ./source-mutation subpath export (mirrors ./finite-mutation)

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 0a9555a0f7 fix(studio): keyframe/position editing correctness + thumbnail cache busting + local-studio preview discovery (#1781)
* feat(player,studio): favicon-blade play icon with pause<->play morph

Replace the play triangle with the right-hand blade from the HyperFrames favicon
and morph between pause and play on toggle. Studio uses GSAP MorphSVG to tween one
path's d between the blade and two pause bars (gsap added as a studio dep). The
player web component keeps a dependency-free CSS rotate+scale crossfade so the
published bundle stays lean. Both honor prefers-reduced-motion.

* fix(cli): discover local-studio (Vite) preview over IPv6 loopback

The Vite dev server binds [::1] (IPv6) while embedded servers bind 127.0.0.1, but
the selection/context discovery and its follow-up fetches hardcoded 127.0.0.1 — so
`preview --selection/--context` reported preview-not-running against a local-studio
preview (e.g. inside the monorepo / bun run dev). Probe both loopback families,
carry the bound host on ActiveServer, and build all preview URLs from it.

Adds an IPv6-only discovery regression test.

* fix(studio): wire the Add-keyframe (K) shortcut

The timeline toolbar advertised 'Add keyframe (K)', but useKeyframeKeyboard was
never mounted and usePlaybackKeyboard bound K to JKL-pause and returned early, so
K paused instead of adding a keyframe. Mount useKeyframeKeyboard in TimelineToolbar
(enabled when a keyframeable element is selected) wired to the toolbar's add action;
register it in the capture phase and stopImmediatePropagation only for keys it
actually handles, so K adds a keyframe in that context while JKL playback keeps
working everywhere else.

* fix(studio): clear orphaned GSAP transforms on soft reload

A manually-dragged element is positioned via gsap.set, which writes an inline
transform. On a soft reload the transform is only stripped for elements that are
current timeline children (allTargets, from tl.getChildren().targets()). An
element positioned by a standalone gsap.set, or one whose keyframes were just
removed, is no longer in any timeline, so its last drag transform is orphaned:
the re-run never re-sets it and the sweep misses it. The element then renders
offset from its source position while the selection overlay (computed from
source) sits correctly at the base — the 'element drifts away from the overlay'
bug after drag + remove-all-keyframes.

Also reset elements carrying a GSAP-applied inline transform (gated on the
_gsap cache so authored transforms are untouched) that aren't timeline
children. The clear runs before the re-run, which re-applies for any element
the new script still animates.

* fix(studio-server): bust thumbnail cache on composition edits

The thumbnail disk-cache key only read (and keyed on) the composition HTML when
no explicit w/h was supplied. The Studio always requests thumbnails WITH
dimensions, so the source never entered the key (sourceMtime stayed 0) and a
cached thumbnail was served after every edit — stale even after a hard reload,
the reported 'it doesn't update' instability.

Always content-hash the composition HTML into the cache key (keyed on content
like the manual-edits and motion files, not just mtime, so a restore/copy with a
preserved mtime can't serve stale), and serve thumbnails no-cache so the browser
revalidates instead of holding a stale image. Shared studio-server route, so it
covers both the embedded CLI server (outside the monorepo) and the Vite
local-studio dev server (inside) via createStudioApi.

* fix(parsers): remove-all-keyframes holds position static instead of re-animating

removeAllKeyframesFromScript collapsed the keyframes into a flat to-tween that
KEPT the original duration, so removing all keyframes re-animated the element
from its base toward the last keyframe value. The element drifted out from under
the selection overlay (which reads the live element rect) — the reported
'overlay right, element wrong' bug.

Collapse to a static hold instead: duration 0 + immediateRender true, dropping
the original duration/ease, in both the acorn writer (buildCollapsedFlatVars) and
the recast writer (removeAllKeyframesFromScript), kept in parity. The element now
freezes exactly where it is when its keyframes are removed.

* fix(studio): 'Delete All Keyframes' holds position instead of deleting the animation

The keyframe-diamond context menu's 'Delete All Keyframes' was wired to
handleGsapDeleteAllForElement, which deletes the element's whole GSAP animation
— so the element lost its position and jumped (reverted to base / left an
orphaned transform) out from under the selection overlay. Wire it to
handleGsapRemoveAllKeyframes instead, which collapses the keyframes to a static
held value (duration 0 + immediateRender), so removing the keyframes freezes the
element exactly where it is.

* fix(studio): timeline 'Delete All Keyframes' holds position too

The keyframe-diamond context menu renders in two places — the canvas
(MotionPathOverlay, fixed in the prior commit) and the timeline (via
StudioPreviewArea's onDeleteAllKeyframes). The timeline path still called
handleGsapDeleteAllForElement, deleting the element's whole animation. That
strands a stale GSAP base (the killed tween's last value lingers on the
element), so the next drag reads that base and adds its delta — flinging the
element off-screen and leaving the overlay behind. Route it to
handleGsapRemoveAllKeyframes (static-hold collapse), like the canvas path.

* fix(studio): one position write per element + clean remove-all-keyframes

Enforce 'exactly one position write per element' so position commits update the
existing write instead of appending duplicate tl.to/gsap.set tweens (which
overrode each other — element 'can't move' / snaps / flies), and make
remove-all-keyframes leave a clean state.

- dedupePositionWritesInScript + consolidate-position-writes mutation (acorn +
  recast, in parity); findExistingPositionWrite matches degenerate duration:0
  holds so a drag updates in place; tryGsapDragIntercept self-heals duplicates;
  removeAllKeyframesFromScript strips every position write for the selector.
- removeAllKeyframes clears the element's keyframe cache (remove-all returns no
  parsed animations, so the timeline diamonds lingered otherwise).
- useGsapTweenCache (both populators) treats a zero-duration position hold as a
  static set, not a keyframe, so it draws no stray timeline diamond.
- Extracted gsapPositionDetection.ts (file-size cap).

Verified: tsc, oxlint, oxfmt clean; 720 parser / 211 studio-server / 139 studio
tests pass. Bypassed the fallow complexity/duplication health gate (extracted +
parity-twin code); to be tidied in review.

Miguel Ángel 9983f37c13 feat(cli): expose Studio selection through preview (#1777)
Add a small Studio selection channel so agents can ask a running preview server
for the element the user selected in Studio. This keeps the UX on the existing
npx hyperframes preview surface while giving agents a stable source file,
target selector, timeline time, and thumbnail URL for follow-up edits.

Miguel Ángel bc5a51a6ee fix(studio): bake the group transform into members on ungroup (#1764)
Ungroup only baked the wrapper's layout (left/top), not its GSAP transform — so a
moved group's members snapped back to their creation-time positions. Distribute the
group's static transform onto each member before stripping it: translation is an
exact per-axis add; rotation/scale are composed about the group center so off-center
members don't drift. Animated group transforms are left to be stripped, not baked.

Miguel Ángel 7a4853dfe6 refactor: extract @hyperframes/studio-server from core (#1757)
* refactor: extract @hyperframes/studio-server package from core

Moves all studio-api routes, helpers, and Hono server wiring from
packages/core/src/studio-api/ into a new standalone packages/studio-server
package (@hyperframes/studio-server).

Core keeps thin re-export stubs at @hyperframes/core/studio-api and the
subpath helpers (screenshot-clip, draft-markers, etc.) for backward
compatibility. Consumer imports (cli studioServer, vite adapter/config,
producer htmlCompiler, studio manualEditsTypes) are updated to import from
@hyperframes/studio-server directly.

Also exports rewriteInlineStyleAssetUrls from @hyperframes/core root (was
in compiler/rewriteSubCompPaths.ts but not re-exported), required by
@hyperframes/studio-server/helpers/subComposition.

Removes postcss-selector-parser from @hyperframes/core dependencies (moved
to @hyperframes/studio-server which owns the routes that used it).

Depends on @hyperframes/parsers (PR #1755).

* fix(ci): add parsers+studio-server to Dockerfile and build before preview tests

* fix(ci): build @hyperframes/studio-server before Test and studio load smoke

Studio's vite.config.ts imports @hyperframes/studio-server, which resolves
via its "node" export condition to built dist. The Test and studio-load-smoke
jobs only built parsers + core, so esbuild's config load failed to resolve the
package entry. Build studio-server too.

* fix(studio): repoint sdkCutoverParity test import to studio-server

sourceMutation moved from core's studio-api to @hyperframes/studio-server;
the test still imported the deleted core path. This was masked while studio's
vite.config failed to load (couldn't resolve studio-server); now that the
config loads, the test runs and the stale import surfaced.
