- Replace all Ionicons with native SF Symbols via expo-symbols SymbolView
- Create reusable Icon wrapper component (src/shared/components/Icon.tsx)
- Remove @expo/vector-icons and lucide-react dependencies
- Refactor explore tab with filters, search, and category browsing
- Add collections and programs data with Supabase integration
- Add explore filter store and filter sheet
- Update i18n strings (en, de, es, fr) for new explore features
- Update test mocks and remove stale snapshots
- Add user fitness level to user store and types
All tabs use shared data, stores, and SwiftUI islands:
- Home: greeting from userStore, featured/popular workouts,
recent activity from activityStore, tappable collections
- Workouts: 50 workouts with SwiftUI Picker category filter,
trainer avatars, workout grid, "See All" links to categories
- Activity: streak banner, SwiftUI Gauges (workouts/minutes/
calories/best streak), weekly Chart, achievements grid
- Browse: featured collection hero, collection grid with emoji
icons, programs carousel, new releases list
- Profile: user card, subscription banner, SwiftUI List with
workout/notification settings (Switches persist via Zustand)
Tab layout uses NativeTabs with SF Symbols and haptic feedback.
