The audio-locked attribute was correctly setting `muted = true` and posting
`set-muted` to the iframe runtime, but on warm-cache reloads of claude.ai
and inside the Claude desktop Electron client, the iframe finishes loading
*after* the parent has already sent control messages — the iframe runtime's
postMessage listener isn't installed yet, so the messages are silently
dropped. Audio plays unmuted with no UI to recover.
Confirmed via:
- "First open" on claude.ai: cold cache, iframe slow → listener up before
`set-muted` lands → audio muted ✅
- "Hard refresh" on claude.ai: warm cache, iframe fast → listener up after
message arrives → message lost → audio plays ❌
- Claude desktop: Electron renderer consistently fast → race always loses
→ audio plays ❌
Fix: add a `{source: "hf-preview", type: "ready"}` event the runtime emits
once `installRuntimeControlBridge` has registered the listener. The player
listens for it and replays current bridge state (`set-muted`, `set-volume`,
`set-playback-rate`). Pre-ready messages are now safe to send — they'll be
replayed once the runtime can receive them.
The replay is idempotent — re-asserting defaults is a no-op — so it's also
safe across iframe reloads (new runtime instance emits ready again).
Tests: 6 new (1 bridge: ready posted on install; 5 player: replays muted /
volume / playback-rate / audio-locked-forced-mute / handles second ready /
ignores ready from wrong source). Suites green: core 1387, player 137.

not attribute stripping as originally hypothesized

* fix(ci): update publish workflow to use bun install
pnpm-lock.yaml was removed in the bun migration but publish.yml
still referenced it. Use bun for install/build, keep pnpm for
publish (publishConfig overrides + --provenance).
* docs: update stale pnpm references to bun across docs and scripts

* 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/*.
