- Rework selection model so any shelter marker can be tapped to select,
not just the nearest three in the bottom sheet list
- Highlight selected shelter with a distinct amber marker icon
- Track user map interaction (pan/zoom) to prevent auto-recentering
- Add reset navigation FAB to re-fit map to user + selected shelter
- Add offline map cache prompt (OK/Skip) with warning banner and retry
- Rewrite MapCacheManager to use passive tile caching via map panning
- Respect system status bar with fitsSystemWindows
