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.
## Summary
Base of the studio UX-review stack (148 findings audited across the studio; 13 critical). This PR hardens the shared `components/ui` primitives that every later PR in the stack builds on.
## Changes
- **Button / IconButton**: visible `focus-visible` outline (studio accent); `disabled:pointer-events-none` removed (replaced with `disabled:cursor-not-allowed`, hover/active gated behind `enabled:`) so disabled buttons can host explain-why tooltips.
- **Tooltip**: keyboard support (`onFocus`/`onBlur` triggers), `role="tooltip"`, Escape-to-hide, viewport flip (top↔bottom) + horizontal clamping. API unchanged — all ~28 call sites unaffected.
- **HyperframesLoader**: `role="status"` on the loader; determinate track is a real `role="progressbar"` with `aria-valuenow/min/max` (was `aria-hidden`).
- **VideoFrameThumbnail**: error event resolves to a static fallback-label tile instead of an infinite shimmer; `motion-reduce` guard.
- **NEW `useDialogBehavior`**: shared modal contract — document-level Escape, Tab focus trap, focus-first-on-open, focus-restore-on-close, `canClose()` veto for dirty-draft guards. Adopted by every modal later in the stack.
- **NEW `SearchInput`**: shared search primitive with required `aria-label`, panel-input token style (kills the two-divergent-search-styles inconsistency in the sidebar).
- **studio.css**: `hf-toast-in/out` + `hf-backdrop-in` keyframes with `prefers-reduced-motion` guards (the previous `animate-in fade-in` classes were dead — no tailwindcss-animate plugin exists).
## Verification
- oxlint 0 errors, oxfmt clean, `tsc --noEmit` clean at stack top
- Full studio suite at stack top: 1189 tests pass
## Stack
PR 1/7 of the studio UX-review fixes. Merges bottom-up; the stack top is fully green (tsc + 1189 tests). Some shared-file edits span PRs, so intermediate branches may not typecheck in isolation.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
The studio shell paints a #0a0a0a body but never declares `color-scheme`,
so browsers render native UA chrome (scrollbars, form controls, focus
rings) in the light palette and the mismatch is obvious — especially
scrollbars, which appear as light tracks sitting on top of a near-black
panel.
Studio doesn't expose a theme toggle; the UI is dark-only. Declaring
`color-scheme: dark` on `:root` lines up the browser-native surfaces
with the rest of the chrome.
Stacked on top of #307. Fixes three mobile UX bugs that made the studio unusable on iPhone Safari — discovered while testing the audio-ownership work from #307 on a physical device.
## Bugs fixed
### 1. Untappable Play button / bottom controls
`#root` was set to `100vh`. iOS Safari reports `100vh` as the **largest** viewport (toolbar hidden) and never shrinks it — so with the toolbar visible, the bottom of the layout sits under it. The Play button + timecode were fully occluded.
### 2. Scrubber not draggable by touch
The seek bar had only `onMouseDown`. Mouse events don't fire for touches on iOS Safari, so nothing responded. You could tap to jump but not drag.
### 3. Safari's horizontal swipe hijacked scrubber drags
Even when the seek bar caught `pointerdown`, `touch-action: manipulation` still let Safari consume horizontal edge-swipes for back-navigation — dragging the scrubber left was impossible.
## What changed
| File | Fix |
|---|---|
| `packages/studio/src/styles/studio.css` | `#root` → `height: 100dvh` with `100vh` fallback. Dynamic viewport height shrinks when the iOS toolbar is visible, so the bottom of `#root` lines up with the visible area. |
| `packages/studio/src/App.tsx` | Two `h-screen` containers → `h-full` so nested children fill the now-dynamic parent instead of asserting `100vh` and overflowing. |
| `packages/studio/index.html` | Added `viewport-fit=cover` so iOS exposes real `env(safe-area-inset-bottom)` values. |
| `packages/studio/src/player/components/PlayerControls.tsx` | Controls row gets `padding-bottom: calc(0.5rem + env(safe-area-inset-bottom))` so it clears the landscape home indicator. Scrubber replaced `onMouseDown` with `onPointerDown` + `setPointerCapture`, plus `touch-action: none` so Safari doesn't hijack horizontal swipes. Added `pointercancel` + window-level `pointerup` fallbacks. |
All desktop code paths are unchanged: `100dvh` falls back to `100vh`, `env(safe-area-inset-bottom)` is `0` off-iOS, Pointer Events subsume Mouse Events on desktop.
## Verified live
Via the `cloudflared` tunnel I ran during review on the factory-series-c-video project:
- iPhone Safari, portrait: Play button now fully visible and tappable. Bottom controls sit just above the URL bar.
- iPhone Safari, landscape: controls clear the home indicator.
- Finger-drag the scrubber left and right: tracks the touch smoothly, finger can leave the 6 px bar height without losing the drag.
- Desktop click-to-seek and click-drag: still work.
- Arrow-key seeking: still works.
## Stacked dependency
Base is `fix/player-audio-ownership-review` (PR #307). Once #307 merges, rebase this branch onto `main` — the changes are fully independent; the stacking is just to avoid waiting on the review for #307 before shipping pure UX wins.
## Test plan
- [x] `tsc --noEmit` on `packages/studio` — clean
- [x] `bun run --filter @hyperframes/studio build` — clean
- [x] Live repro on iPhone Safari via cloudflared tunnel: Play button tappable, scrubber drags with touch
- [ ] Android Chrome sanity pass before release (same Pointer Events code path, but worth eye-balling)
* feat: initial code port from hyperframes-internal
Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)
Includes regression test suite with Docker-based test harness.
All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.
