Release v1.7.0: installable offline app, Android/iOS, faster first paint · dominikpeter/imposter

New

Installable app (PWA): Settings → Install app (Android, computers), or Share → Add to Home Screen on iPhone (Settings shows the steps). It opens full-screen with the mask icon.
Works offline: after the first visit, the one-phone game loads and plays without a connection. Rooms and AI need one.
Android and iOS apps with Capacitor that load the live site, so every web release updates them too. just app-android builds an APK; just app-ios opens Xcode.

First paint is ~3× sooner: the start screen's top is in the server HTML (2.0 s → 0.7 s on a mid-range phone over 4G), and the cards deal in once the app is live.
Profiling showed the server functions must sit next to the database (US east). Pinned to iad1 and measured; each room request now reads the room and its players in parallel.

The service worker never caches Next's route data (it must match the deployed build) or /admin, keeps only the start page for offline use, and starts a fresh cache with every release.
The iOS app declares its app-bound domain, which iOS requires before it runs the offline worker.
