This Phase includes a Progressive Web App foundation for Android, iPhone and tablets: installable shell, offline fallback and share-ready property URLs.
Use Chrome → menu → Add to Home screen / Install app.
Use Safari → Share → Add to Home Screen.
Service-worker foundation included. Production push still needs a push provider and user consent workflow.
The app shell and offline page are cached. Sensitive account pages are not cached.
Each property URL can be shared or turned into a QR code using your preferred QR library/provider.
Native App Store / Play Store packages are a separate build. The PWA gives you a mobile-app experience immediately without duplicating the backend.
