Miguel Ángel f7d63fbebd fix(studio): address PR review — add tests, strip GSAP transform for rotation, remove dead exports
Addresses review feedback from Rames and Vai:

1. Add 7 new tests for createStudioPositionSeekReapplyScript:
   box-size reapplication, GSAP translate stripping (identity removal,
   scale+translate preservation, transform:none no-op), and rotation-
   only elements with GSAP-baked translate.

2. Add pinning test for the PiP-over-sub-composition selection bug:
   elementsFromPoint returns [pipVideo, subCompRoot, sfChromeImg] as
   siblings — assert the topmost (pipVideo) wins.

3. Apply stripGsapTranslateFromTransform to rotation-only elements
   too, not just path-offset elements. A rotation-only element with
   a GSAP-animated translate would have its position clobbered.

4. Remove dead exports: getPreviewLocalPointer,
   buildRasterClickSelectionContext, getPreviewPlayer,
   seekStudioPreview, PreviewPlayerCompat, PreviewLocalPointer from
   studioPreviewHelpers.ts. Unexport resolvePreviewLocalPointer.

@hyperframes/studio

Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

npm install @hyperframes/studio

What it does

The studio is a React application with:

  • Visual timeline — drag, resize, and arrange elements on tracks
  • Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
  • Live preview — see changes in real time as you edit
  • Composition inspector — view and modify element properties

Development

The studio is embedded in the hyperframes preview command. To develop the studio UI itself:

cd packages/studio
bun run dev        # Start Vite dev server
bun run build      # Build for production
bun run typecheck  # Type-check
