The "purpose": "any maskable" property caused Android to apply
adaptive icon treatment (circular/rounded square mask) to icons
that were not designed with safe zones for maskable display.
This resulted in the icon being incorrectly cropped on Android home screen.
Removed maskable purpose while keeping useful PWA enhancements:
- description field
- categories
- start_url and scope
Icons now display correctly without cropping.

Implements Progressive Web App notification capabilities:
- Service Worker foundation for PWA installability and offline support
- Browser notification toggle in side menu with permission management
- Local notifications triggered on new messages (channels, DMs, pending)
- App Badge API integration showing total unread count on app icon
- Smart notification logic (only when app hidden, only for NEW messages)
- Graceful degradation for unsupported browsers
Technical details:
- Service Worker with network-first fetch strategy for dynamic content
- Notification permission stored in localStorage (mc_notifications_enabled)
- Delta-based notification tracking (prevents spam on page load)
- Notification tag prevents duplicate alerts
- App badge auto-clears when user returns to app
Limitations (documented):
- Android may freeze background JS after 5-10 minutes (OS behavior)
- Full "wake device" support requires Web Push API (future enhancement)
- Works best for active users who check app regularly
