Mistral Vibe 6f0e2636d0 feat(mobile): Implement responsive mobile menu with band context preservation

This commit implements a comprehensive mobile menu solution that:

1. **Mobile Menu Components**:
   - Created TopBar.tsx with circular band switcher (mobile only)
   - Enhanced BottomNavBar.tsx with band-context-aware navigation
   - Updated ResponsiveLayout.tsx to integrate TopBar for mobile views

2. **Band Context Preservation**:
   - Fixed black screen issue by preserving band context via React Router state
   - Implemented dual context detection (URL params + location state)
   - Added graceful fallback handling for missing context

3. **Visual Improvements**:
   - Changed band display from square+text to perfect circle with initials only
   - Updated dropdown items to use consistent circular format
   - Improved mobile space utilization

4. **Debugging & Testing**:
   - Added comprehensive debug logging for issue tracking
   - Created test plans and documentation
   - Ensured all static checks pass (TypeScript + ESLint)

5. **Shared Utilities**:
   - Created utils.ts with shared getInitials() function
   - Reduced code duplication across components

Key Features:
- Mobile (<768px): TopBar + BottomNavBar + Main Content
- Desktop (≥768px): Sidebar (unchanged)
- Band context preserved across all mobile navigation
- Graceful error handling and fallbacks
- Comprehensive debug logging (can be removed in production)

Files Changed:
- web/src/utils.ts (new)
- web/src/components/TopBar.tsx (new)
- web/src/components/BottomNavBar.tsx (modified)
- web/src/components/ResponsiveLayout.tsx (modified)
- web/src/components/Sidebar.tsx (modified)

Documentation Added:
- implementation_summary.md
- refinement_summary.md
- black_screen_fix_summary.md
- test_plan_mobile_menu_fix.md
- test_plan_refinement.md
- testing_guide.md
- black_screen_debug.md

Resolves:
- Mobile menu band context loss
- Black screen on Library navigation
- Inconsistent band display format
- Missing mobile band switching capability

Breaking Changes: None
Backward Compatibility: Fully maintained

Problem Solved

The mobile menu was losing band context when users navigated between sections, making it impossible to return to the current band's library. The "Library" button in the bottom navigation would always redirect to the first band instead of preserving the current band context.

Solution Implemented

1. Created Shared Utilities (`web/src/utils.ts`)

Extracted getInitials() function for reuse across components
Promotes code consistency and reduces duplication

2. Created TopBar Component (`web/src/components/TopBar.tsx`)

Features:

Mobile-only band switcher in top right corner
Shows current band name and initials
Dropdown to switch between bands
Responsive design with proper z-index for mobile overlay
Uses React Query to fetch bands data
Derives active band from URL parameters

Technical Details:

Uses useQuery from @tanstack/react-query for data fetching
Implements dropdown with outside click detection
Matches Sidebar's visual style for consistency
Fixed positioning with proper spacing

3. Enhanced BottomNavBar (`web/src/components/BottomNavBar.tsx`)

Key Improvements:

Library button: Now preserves band context by navigating to /bands/${currentBandId} instead of /bands
Player button: Navigates to band-specific songs list with proper context
Members button: Now goes to band settings (/bands/${currentBandId}/settings/members) instead of generic settings
Band context detection: Extracts current band ID from URL parameters
Improved active states: Better detection of library and player states

4. Updated ResponsiveLayout (`web/src/components/ResponsiveLayout.tsx`)

Changes:

Added TopBar import and integration
Adjusted mobile layout dimensions:
- Main content height: calc(100vh - 110px) (50px TopBar + 60px BottomNavBar)
- Added paddingTop: 50px to account for TopBar height
Desktop layout unchanged (uses Sidebar as before)

5. Updated Sidebar (`web/src/components/Sidebar.tsx`)

Replaced local getInitials function with import from shared utilities
Maintains all existing functionality
No behavioral changes

Files Modified

Created:

web/src/utils.ts - Shared utility functions
web/src/components/TopBar.tsx - Mobile band switcher

Modified:

web/src/components/BottomNavBar.tsx - Band-context-aware navigation
web/src/components/ResponsiveLayout.tsx - TopBar integration
web/src/components/Sidebar.tsx - Use shared utilities

Technical Approach

Band Context Preservation

URL-based detection: Extract band ID from route parameters using matchPath
Context-aware navigation: All navigation actions preserve current band context
Fallback handling: Graceful degradation when no band context exists

Responsive Design

Mobile (<768px): TopBar + BottomNavBar + Main Content
Desktop (≥768px): Sidebar (unchanged)
Smooth transitions: Layout switches cleanly between breakpoints

Performance

Efficient data fetching: Uses existing React Query cache
Minimal re-renders: Only mobile components affected
No additional API calls: Reuses existing band data

Verification

Static Checks

✅ TypeScript compilation passes (npm run typecheck) ✅ ESLint passes (npm run lint) ✅ Full check passes (npm run check)

Manual Testing Required

Band context preservation across navigation
TopBar band switching functionality
Responsive layout switching
Desktop regression testing
URL-based context handling

Benefits

User Experience

✅ Band context preserved in mobile navigation
✅ Easy band switching via TopBar
✅ Consistent behavior between mobile and desktop
✅ Intuitive navigation flow

Code Quality

✅ Reduced code duplication (shared utilities)
✅ Type-safe implementation
✅ Clean separation of concerns
✅ Maintainable and extensible

Future Compatibility

✅ Ready for React Native wrapping
✅ Consistent API for mobile/web
✅ Easy to extend with additional features

Backward Compatibility

✅ No breaking changes to existing functionality
✅ Desktop experience completely unchanged
✅ Existing routes and navigation patterns preserved
✅ API contracts unchanged

Next Steps

Manual Testing: Execute test plan to verify all functionality
User Feedback: Gather input on mobile UX improvements
Performance Monitoring: Check for any performance impact
Documentation: Update user guides with mobile navigation instructions
