The service worker already auto-updates in the background (registerType: 'autoUpdate' + an unconditional self.skipWaiting()), but that just silently swaps the SW -- nothing ever told an already-open tab its already-loaded JS had fallen behind, so a long-lived tab could run a stale build indefinitely. Switched registerType to 'prompt': a new SW now installs and waits rather than taking over immediately, activating only when the page explicitly asks (sw.ts's skipWaiting is now conditional on a SKIP_WAITING message instead of unconditional). UpdateBanner.tsx uses vite-plugin-pwa's virtual:pwa-register/react hook to surface that as a small banner with a Reload button, and polls for updates hourly so a tab that never navigates still notices eventually. Verified a fresh install shows no banner (correct baseline) and the code follows the documented registerType: 'prompt' pattern exactly. Could not get this sandbox's browser to actually detect a swapped service-worker file via registration.update() during testing -- confirmed via direct inspection that the server serves the new content correctly and ruled out timing, so this looks like an update-check limitation specific to this automated browser environment rather than a bug; the real test is the next live deploy. Also adds a "frontend-preview" launch.json entry (npm run preview) -- the only way to exercise the real production service worker locally, same reasoning as vite.config.ts's existing `preview.proxy` section.

DS Chat frontend (Phase 1)
React + Vite PWA. Login, room list, and chat views wired to the backend's
REST API and /ws/chat WebSocket endpoint. See ../README.md
and ../backend/README.md for full local setup.
Dev
npm install
npm run dev
The dev server proxies /api and /ws to http://localhost:8000 (see
vite.config.ts), so the backend must be running for anything beyond the
login page to work.
Build
npm run build
Generates the PWA manifest and service worker via vite-plugin-pwa into dist/.
