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

# Mobile Menu Refinement - Implementation Summary
## Changes Implemented
### 1. Band Display Format Fix (TopBar.tsx)
**Issue**: Band was displayed as square with initials + full text
**Fix**: Changed to perfect circle with initials only
**Code Changes**:
```tsx
// Before (square + text)
<div style={{ width: 24, height: 24, borderRadius: 6 }}>
{activeBand ? getInitials(activeBand.name) : "?"}
</div>
<span style={{ fontSize: 13, fontWeight: 500 }}>
{activeBand?.name ?? "Select band"}
</span>
// After (circle only)
<div style={{
width: 32,
height: 32,
borderRadius: "50%", // Perfect circle
fontSize: 12
}}>
{activeBand ? getInitials(activeBand.name) : "?"}
</div>
```
**Visual Impact**:
- ✅ Cleaner, more compact display
- ✅ Consistent with mobile design patterns
- ✅ Better use of limited mobile screen space
- ✅ Matches Sidebar's circular band display style
### 2. Black Screen Debugging (BottomNavBar.tsx)
**Issue**: Library navigation resulted in black screen
**Fix**: Added comprehensive debug logging to identify root cause
**Debug Logging Added**:
```tsx
// Band context tracking
console.log("BottomNavBar - Current band ID:", currentBandId, "Path:", location.pathname);
// Library navigation debugging
console.log("Library click - Navigating to band:", currentBandId);
if (currentBandId) {
navigate(`/bands/${currentBandId}`);
} else {
console.warn("Library click - No current band ID found!");
navigate("/bands");
}
```
**Debugging Capabilities**:
- ✅ Tracks current band ID in real-time
- ✅ Logs navigation paths
- ✅ Identifies when band context is lost
- ✅ Provides data for root cause analysis
### 3. Dropdown Consistency (TopBar.tsx)
**Enhancement**: Updated dropdown band items to use circles
**Code Changes**:
```tsx
// Before (small square)
<div style={{ width: 20, height: 20, borderRadius: 5 }}>
// After (circle)
<div style={{ width: 24, height: 24, borderRadius: "50%" }}>
```
## Files Modified
### Updated Files:
1. **`web/src/components/TopBar.tsx`**
- Band display: Square → Circle
- Removed text display
- Updated dropdown items to circles
- Improved visual consistency
2. **`web/src/components/BottomNavBar.tsx`**
- Added debug logging for band context
- Enhanced Library navigation with error handling
- Improved debugging capabilities
### Unchanged Files:
- `web/src/components/Sidebar.tsx` - Desktop functionality preserved
- `web/src/components/ResponsiveLayout.tsx` - Layout structure unchanged
- `web/src/pages/BandPage.tsx` - Content loading logic intact
- `web/src/App.tsx` - Routing configuration unchanged
## Technical Details
### Band Context Detection
- Uses `matchPath("/bands/:bandId/*", location.pathname)`
- Extracts band ID from URL parameters
- Preserves context across navigation
- Graceful fallback when no band selected
### Debugging Strategy
1. **Real-time monitoring**: Logs band ID on every render
2. **Navigation tracking**: Logs before each navigation action
3. **Error handling**: Warns when band context is missing
4. **Fallback behavior**: Navigates to `/bands` when no context
### Visual Design
- **Circle dimensions**: 32×32px (main), 24×24px (dropdown)
- **Border radius**: 50% for perfect circles
- **Colors**: Matches existing design system
- **Typography**: Consistent font sizes and weights
## Verification Status
### Static Checks
**TypeScript**: Compilation successful
**ESLint**: No linting errors
**Full check**: `npm run check` passes
### Manual Testing Required
- [ ] Band display format (circle only)
- [ ] Library navigation debugging
- [ ] Error handling verification
- [ ] Band context preservation
- [ ] Responsive layout consistency
## Expected Debug Output
### Normal Operation
```
BottomNavBar - Current band ID: "abc123" Path: "/bands/abc123/settings/members"
Library click - Navigating to band: "abc123"
```
### Error Condition
```
BottomNavBar - Current band ID: null Path: "/settings"
Library click - No current band ID found!
```
## Next Steps
### Immediate Actions
1. **Execute test plan** with debug console open
2. **Monitor console output** for band ID values
3. **Identify root cause** of black screen issue
4. **Document findings** in test plan
### Potential Fixes (Based on Debug Results)
| Finding | Likely Issue | Solution |
|---------|-------------|----------|
| `currentBandId: null` | Context loss on navigation | Improve context preservation |
| Wrong band ID | URL parsing error | Fix matchPath logic |
| API failures | Network issues | Add error handling |
| Race conditions | Timing issues | Add loading states |
### Finalization
1. **Remove debug logs** after issue resolution
2. **Commit changes** with clear commit message
3. **Update documentation** with new features
4. **Monitor production** for any regressions
