- Remove debug artifact from login page ('Use Link component: HOME')
- Full icon set: 48/72/96/128/144/152/192/384/512 + maskable variants
- Proper manifest: display_override, shortcuts, categories, scope
- Better service worker: offline fallback page, pre-caching, stale-while-revalidate
- Custom install banner (Android beforeinstallprompt + iOS instructions)
- Connection status indicator (online/offline toast)
- Updated index.html with proper favicon sizes and meta tags
