Miguel Ángel 2a2a88ce1f fix(studio): center vertical composition thumbnails in sidebar (#820)
* feat(studio): add pasteboard background to preview viewport

Adds bg-neutral-800 to the preview viewport so the area outside the
canvas is visually distinct from the composition content — consistent
with professional video editors (Premiere, DaVinci, Figma).

* feat(studio): pasteboard background and canvas outline around preview

- NLEPreview: viewport gets bg-neutral-700 (#404040) as the pasteboard
  color surrounding the canvas — distinct from the app chrome (#0a0a0a)
- Player wrapper: drop bg-black so the pasteboard shows around the canvas
  (loading overlays still cover the area with bg-black during load)
- Player: set host background to transparent via inline style (overrides
  :host { background: #000 } in shadow DOM), and inject a style rule into
  the open shadow root so .hfp-container has overflow:visible and the
  canvas iframe gets a thin white ring + soft drop-shadow — making the
  canvas boundary legible against the pasteboard

* fix(studio): center vertical composition thumbnails in sidebar

Portrait (and other non-16:9) compositions were pinning to the top-left
of the 80x45 thumbnail slot because transform-origin was '0 0'. Compute
the centering offsets from the scaled dimensions and apply them as
left/top so any aspect ratio renders centred in the slot.

@hyperframes/studio

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

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
