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.

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 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)
