* 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(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)

Run `fallow fix --auto-fixable` to remove `export` keywords from symbols
fallow's reachability analysis identifies as unused. Keeps only the cases
where the symbol is still referenced internally in its own file (so
removing `export` doesn't surface a new oxlint `no-unused-vars` error).
Result: fallow dead-code findings drop from 276 → 208 (68 fewer unused
exports), with no behavior change — each symbol is still defined and used
exactly the same way within its file.
Reverted ~20 files where fallow's auto-fix would have created cascading
"declared but never used" lint errors — those are cases where the symbol
isn't used at all, and properly cleaning them up means deleting the
declaration, not just dropping `export`. Better to land that as a
separate, narrower PR rather than mixing it into a mechanical de-export.
Also reverted four false positives where fallow missed real consumers:
- `captureCost.ts` (renderOrchestrator has two separate import blocks
from the same module; fallow only saw the first)
- `propertyPanelHelpers.ts`, `domEditingLayers.ts` (real internal uses
fallow's reachability missed)
- `render.ts` (functions imported via `await import()` dynamic import,
which fallow's static analysis doesn't follow)
Test plan: bun run --filter '*' typecheck (clean), oxlint + oxfmt clean,
cli/core/studio/engine vitest suites pass (335 + 917 + 576 + 605 tests).
* refactor: split useTimelinePlayer.ts and hyperframes-player.ts into focused modules (<500 LOC each)
* fix(ci): scope 500 LOC check to packages/studio, add allowlist for grandfathered files
* feat(cli): Linux ARM64 support — auto-install Chromium on DGX Spark / GB10 / Jetson
Chrome Headless Shell has no Linux ARM64 binary. On arm64 Linux:
- Detects the platform automatically
- Tries to auto-install system Chromium via apt-get (works on Ubuntu/Debian ARM)
- Falls back to clear manual instructions with exact commands
- 'hyperframes browser ensure' guides through the setup interactively
- After setup, all render commands work without any flags
* fix(ci): disable Windows Defender real-time monitoring to prevent EPERM builds
Path exclusions are insufficient — Defender re-scans new files created
during bun install before the exclusion takes effect. Disable real-time
monitoring for the entire job duration instead (standard CI practice).
* refactor(studio): split all files >500 LOC + extract useToast, delete allowlist
All 11 large files split into focused modules under 500 LOC.
App.tsx extracted toast logic into useToast hook (493 LOC now).
.filesize-allowlist deleted — no longer needed.
* fix: remove unused imports from split files, extract useToast from App.tsx
App.tsx: 504 → 493 lines (toast logic extracted to useToast hook)
timelineDOM.ts: remove unused imports from re-export pattern
MotionPanel.tsx: remove unused clampStudioCustomEasePoints import
studioMotionOps.ts: remove unused StudioGsapMotionDirection import
* fix(ci): use Set-MpPreference to fully disable Windows Defender (both jobs)
* fix(producer): use node --experimental-strip-types instead of tsx for build:fonts
Eliminates the tsx binary dependency that Windows Defender locks during
bun install, causing EPERM errors. Node 22.6+ strips TypeScript types
natively with no external binary.
* chore: remove .filesize-allowlist — App.tsx is now 493 lines (<500)
* fix(ci): disable Windows Defender before checkout to prevent all EPERM races
* fix(producer): skip build:fonts if fontData.generated.ts already exists
The generated file is tracked in git, so CI doesn't need to regenerate
it. This avoids @fontsource/inter node_modules access on Windows which
triggers EPERM from Defender scanning during bun install.
The generated JavaScript used manual single-quote escaping
(replace(/\\/g, '\\\\').replace(/'/g, \"'\\\\''\")) which missed
newlines, carriage returns, and other special characters. Captions
containing line breaks would produce syntactically broken JS.
Use JSON.stringify which handles all JS string special characters
correctly, including newlines, unicode, and control characters.

## Summary
This stacked PR makes caption overrides refresh-safe.
Caption edits are still saved to `caption-overrides.json`, but override targets are now stable across preview refreshes and regenerated caption HTML.
## Architecture
- **Stable word identity**: generated caption HTML preserves optional transcript word IDs in the `TRANSCRIPT` array and emits those IDs on word spans.
- **Parser continuity**: the caption parser preserves existing transcript word `id` fields instead of regenerating index-only identity.
- **Override loading**: Studio loads saved overrides by `wordId` first, with the existing `wordIndex` fallback kept for older overrides.
- **Idempotent runtime wrapping**: transform overrides reuse an existing `data-caption-wrapper="true"` wrapper instead of nesting wrappers on every refresh.
- **Animation compatibility**: overrides still wrap the word so inner word-level GSAP animation can continue to target the original span.
## User Impact
Users can edit caption word position, scale, rotation, color, opacity, font size, font weight, and font family, then refresh without overrides drifting to the wrong word or accumulating nested wrappers.
## Main Files
- `packages/core/src/runtime/captionOverrides.ts`
- `packages/studio/src/captions/generator.ts`

* fix(studio): load @hyperframes/player lazily to support SSR
Player.tsx had a bare `import "@hyperframes/player"` at module scope. The
player package registers a class that extends HTMLElement as a side effect,
and HTMLElement doesn't exist in a Node server runtime. Any consumer that
imported from @hyperframes/studio during server-side rendering (e.g. the
Next.js App Router evaluating a client component for SSR) threw
`HTMLElement is not defined`.
Move the import inside the mount effect via dynamic `import(...)` so it
only runs in the browser, and wire up a cancellation flag and deferred
cleanup so a fast unmount doesn't leak listeners or DOM nodes.
* fix(studio): remove .js extensions from captions-internal imports
The captions module imported sibling files as `./types.js` and
`./parser.js`. That's legal ESM TypeScript, but Turbopack (and other
bundlers) refuse to resolve those specifiers against .ts files when the
package is consumed from node_modules — the rest of @hyperframes/studio
uses extensionless imports for that reason.
Align captions with the rest of the codebase so the package builds
without bundler-specific configuration in consumers.
* chore: release @hyperframes/player@0.2.7 and @hyperframes/studio@0.2.9
Ships the root-timeline resolution fix (#247), the SSR-safe player load,
and the captions import cleanup.
## Summary
- **New skill:** **`marker-highlight`** — integrates [MarkerHighlight.js](https://github.com/Robincodes-Sandbox/marker-highlight) into HyperFrames compositions. Canvas-based animated text highlighting with 5 drawing modes: marker pen, circle, burst, scribble, and sketchout.
- **Studio fix:** added missing `captionSync` to useEffect dependency array (oxlint exhaustive-deps)
- **Studio fix:** `loadOverrides` now checks `res.ok` before parsing, preventing 404 console noise on projects without captions
## Skill details
The skill documents the non-obvious GSAP integration pattern discovered during development:
1. **One highlighter per container** — the library clears ALL `.highlight` divs from the shared parent on init, so multiple instances on sibling marks conflict
2. **`data-color`** **\+** **`data-original-bgcolor`** — prevents the CSS background-color flash that occurs when the library reads and clears the mark's background
3. **Canvas pre-draw + clear + reanimate** — `animate: false` pre-draws statically, canvases are hidden, then cleared and shown with `reanimateMark()` at trigger time for clean animated reveals
4. **`onReverseComplete`** **for rewind** — hides highlight divs when the timeline seeks backward past the trigger point
## Test plan
- [ ] `npx hyperframes lint` passes on test-composition
- [ ] Studio preview shows marker highlight on "something" at 1s, circle on "love" at 2.2s
- [ ] Rewind past trigger points hides highlights
- [ ] No 404 console errors for caption-overrides.json on non-caption projects

* fix(studio): address caption designer PR feedback
Fixes from review comments on feature/caption-designer (#180):

no longer produce NaN rgba values
- fix(sync): log auto-save failures instead of silently swallowing them
- fix(sync): check res.ok before parsing caption-overrides response
- refactor(components): extract Section, Row, inputCls into shared.tsx
to eliminate duplication between CaptionPropertyPanel and

counter-based group IDs
- fix(store): read selectedGroupId from state param instead of get() to

* fix(studio): address remaining caption designer feedback
Overlay: handle both per-word spans (generator output) and grouped text
nodes (existing templates). Wraps text nodes into individual spans on
demand so the overlay can target words in any caption format.
Property panel: add Typography (font, size, weight, spacing) and Color
(color, active, dim, opacity) sections alongside existing Position and
Transform controls.
Timeline: move caption timeline into a dedicated flex-shrink-0 section
below the main timeline tracks instead of inside the scrollable area.
Gives it fixed 60px height that's always visible.
Caption overrides: classify color tweens by comparing target color to
the dim baseline instead of relying on timeline position order. This
handles compositions with custom color tweens correctly.
App.tsx: remove polling interval, rely on runtime postMessage events
for caption detection. Add clarifying comment on why useEffect is
appropriate (external event subscription).

* fix(studio): restore cssScale in overlay coordinate conversion
getBoundingClientRect() on iframe-internal elements returns coordinates
in the iframe's native resolution (1920x1080), not the CSS-scaled
display size. The cssScale multiplier is needed to convert to parent
window coordinates. The earlier removal was incorrect — it only worked
at 1:1 scale.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): fix reversed scaling on left-side corner handles
Scale interaction used horizontal dx from start position, which goes
negative when dragging left handles outward. Now uses distance from box
center — dragging away from center increases scale regardless of which
corner handle is used.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): make rotation respond to horizontal drag only
Rotation handle sits directly above the word, so atan2-based rotation
barely responds to left/right movement. Replace with linear horizontal
mapping: drag right = clockwise, drag left = counter-clockwise,
200px = 90 degrees. Vertical movement is ignored.

## Summary
- Rewrite script-to-style mapping as an energy detection table (high → low) with mandatory animation requirements: karaoke baseline, 2+ highlight techniques, kinetic exits
- Replace `tl.call()` per-frame audio-reactive pattern with group-level GSAP tweens — read peak bass/treble for each group's time range and modulate entrance intensity at build time, no per-frame callbacks needed
- Add transcript quality check with automatic retry rules (>20% music tokens = retry with larger model)
- Add caption word structure lint rule (`.caption-group` + `<span>`) for studio editor compatibility
- Add multilingual model guidance and decision tree for model selection
## Test plan
- [ ] Skill files render correctly as markdown
- [ ] Cross-references between SKILL.md, dynamic-techniques.md, and transcript-guide.md resolve correctly
- [ ] `dynamic-techniques.md` audio-reactive section uses `tl.to()`/`tl.set()` only, no `tl.call()` loops
