Replay: pauses are no longer compressed — steps fire on absolute recorded
clocks (1:1 with the recording), the cursor stays on the track, a 200ms
settle follows scrolls so the next click resolves on the scrolled page,
and the clock re-anchors after page loads (load time is not recorded time).

Version + hot overlay: the extension version now comes from the root
package.json; the server publishes the current version and the overlay
module (overlay.js + overlay.css) at /api/ext/manifest + /api/ext/assets
(POST /api/ext/publish, manifest written last as the commit point). The
content script imports the server overlay straight from its URL — public
assets answer ACAO * because page-origin imports are the only module path
that works in an isolated world (blob/data imports and eval are all
blocked by the MV3 CSP) — and falls back to the statically bundled copy
on any failure; the version gate never downgrades the UI below the core.
Core updates surface as a popup banner linking to /download; the download
page shows the published version and versioned zips (npm run package also
emits them). make ext-publish ships the overlay from a built dist.

E2E covers the whole hot-overlay round trip: publish a marked 9.9.9
overlay, reload → data-overlay-source="remote", popup banner, dead-server
fallback → "bundled", then republish the pristine assets.

An MV3 service worker is killed after ~30 s of idle time, so parking the
recording buffer in background memory (pending + 10-min auto-save timer)
was unreliable: the timer never fired and Save could hit a restarted
worker with an empty buffer. Now recorderStop uploads the media, submits
the report with the auto-title right away, and only then opens the
composer. Save patches title/description (PATCH /api/reports/{token}),
Discard deletes the report — both are token-based and survive worker
restarts. recorder_submit is replaced by recorder_edit/recorder_discard
{token}.

- Popup: project dropdown (list_projects + settings_save defaultProjectId);
  switching refreshes the last-report card and panel link immediately.
- Recording stop no longer submits blindly: the buffer goes pending and a
  composer opens in the tab with title (prefilled) + description, Save
  (Ctrl+Enter, copies the share link) or two-step Discard; unanswered
  pending recordings auto-save after 10 minutes, and starting a new
  recording auto-saves a pending one. Composer survives navigation.
- WebM is now a square cursor-following crop (shared cursorCropRect helper
  with the GIF path), source dimension raised to 1280 so the 512px crop is
  native-resolution at DPR 1; full-frame 800px stays as fallback.
- e2e: second project + popup switcher asserts, composer save (typed
  title/description verified on server), keyboard-driven discard flow,
  ffprobe square-video assertions (512x512 VP8).

- MV3 extension for Chrome and Firefox: single codebase, per-entry IIFE
  builds (background / content / options), manifests generated per target
- Background service worker owns all networking (Bearer token from
  storage.local), captureVisibleTab (windowId!), recorder event buffer
  with offset_ms and auto-screenshots on clicks
- Content overlay in a closed shadow root (constructable stylesheets,
  kit CSS fetched from assets/style.css with /assets URL rewrite);
  PickerLayer, NoteComposer (autofocus, Ctrl+Enter submit),
  RecorderBar (step counter, note, stop)
- Options page: server URL, login, default project
- Recorder steps link screenshots by uploaded file id (server accepts
  attachment id or file id); environment/element JSONB serialized with
  mode="json" (datetime captured_at broke inserts)
- e2e harness: headless Chromium + extension, note + recording flows
- Makefile, docker-compose.prod.yml (caddy :8081 + static panel),
  deploy/Caddyfile, README (ru) with extension install and /assets notes
