- fix LocationTracker to only activate when logged in and hoist to root layout for persistent tracking
- adjust InstallPrompt positioning to avoid overlapping bottom navigation
- throttle map cluster recomputation to reduce unnecessary work during pan/zoom
- clear cached items on logout to prevent cross-driver data leakage
Add full PWA support (icons, manifest, service worker, pwa lib and bridge) and introduce install/offline UI. Generate app icons via a new scripts/generate-icons.js and include multiple icon sizes in public/icons; update manifest and layout head meta/preconnect. Revamp global styles (globals.css) with new utilities, animations, spacing for bottom nav, card shadows, skeletons and accessibility tweaks. Polish major screens (login, collections, map, settings) with improved headers, loading states, touch/press feedback, and layout adjustments; add new components (InstallPrompt, OfflineIndicator, PWABridge) and update various components to match new visual/UX patterns. Update Dockerfile to generate icons and use Next.js static export output (/out) for nginx, and bump package setup to support icon generation.
