Initial scaffold: Beat Pocket MV3 extension
- manifest.json with MV3 config, host permissions for beat-battle.net - content/detector.ts: route + overlay observer, emits bbp:phase events - content/layout.ts: defensive mobile-first layout reflow - content/chat-drawer.ts: bottom-sheet drawer, dispatches synthetic events through site's own React-managed textarea + button (preserves auth, rate-limit, mute, profanity guards) - content/util/selectors.ts: text- and role-based fallback chain - content/util/ws-proxy.ts: lightweight WebSocket instrumentation, no payload capture - content/inject.css: mobile overrides using site's existing --bb-* vars - background.js: MV3 service worker stub - package.json + tsconfig.json + esbuild.config.mjs: build pipeline - icons/: 16/32/48/128 placeholder PNGs (chili-red disc) - docs/PLAN.md: full V1 architecture, risks, scope - README.md: scope, dev workflow (load unpacked), tech

/**
|

* chat-drawer.ts — bottom sheet chat UI.
|
||||
*
|
||||
* Display:
|
||||
* - We clone the existing chat scrollback (if found) and render into our
|
||||
* own <ul>-style list. We update it every 1.5s by re-cloning the source.
|
||||
* - We do NOT move the original node — we read-only display.
|
||||
*
|
||||
* Send (the clever bit):
|
||||
* - Our composer dispatches a real InputEvent + KeyboardEvent(Enter) on
|
||||
* the original site's chat textarea + a click on its submit button.
|
||||
* - That keeps every server-side guard (rate limit, mute, profanity)
|
||||
* intact — the React reducer thinks the user typed in their UI.
|
||||
* - If the React flow is broken (e.g. their chat was redesigned), the WS
|
||||
* proxy can fall back to a direct socket send.
