Opens this same origin on another device. Does not install a native app, and does not sync data by itself — each device keeps its own IndexedDB unless you configure Sync below.
- Install / Add to Home Screen from the browser menu for an app-like icon (PWA).
- After the first visit, the service worker + local IndexedDB keep the app usable offline. Losing internet ≠ losing the app once cached.
- localhost cannot be opened usefully on a phone for E2EE — deploy over HTTPS (GitHub Pages / Cloudflare Pages / Netlify) or a TLS tunnel, then scan this QR. See docs/SHIP.md.
