  "title": "Fix Mobile Responsiveness Issues - Layout Breaks on Screens < 768px",
  "body": "## 🐛 Problem Description\n\nThe sealed auction platform had significant mobile responsiveness issues, particularly on screens smaller than 768px. The layout would break, auction cards would overflow, and the user experience was poor on mobile devices.\n\n### Specific Issues Identified:\n- **Header Layout**: Fixed horizontal layout causing overflow on mobile\n- **Navigation Tabs**: No mobile-specific styling, buttons too small for touch\n- **Auction Cards**: Long titles and descriptions overflowing containers\n- **Grid Layout**: Improper breakpoints causing layout breaks\n- **Modal Dialogs**: Fixed width without mobile adjustments\n- **Form Layouts**: Grid layouts not stacking properly on mobile\n- **Text Overflow**: No truncation for long content\n\n## 🛠️ Solution Implemented\n\n### Responsive Design Fixes:\n\n#### 1. **Header Responsiveness**\n- Changed from fixed horizontal to responsive flex column/row layout\n- Added mobile-specific text sizing (`text-lg sm:text-2xl`)\n- Hidden \"Blockchain\" badge on mobile, shown on sm+ screens\n- Made wallet button full-width on mobile with responsive text\n\n#### 2. **Navigation Tabs**\n- Converted to vertical stack on mobile, horizontal on sm+ screens\n- Added abbreviated labels for mobile (List, Create, Bids)\n- Proper spacing adjustments for touch targets\n- Responsive button sizing and padding\n\n#### 3. **Auction Cards Grid**\n- Updated breakpoints: `grid-cols-1 sm:grid-cols-2 lg:grid-cols-3`\n- Reduced gap spacing on mobile (`gap-4 sm:gap-6`)\n- Fixed card padding for mobile screens (`p-4 sm:p-6`)\n\n#### 4. **Auction Card Content**\n- Added text truncation for long titles with `truncate flex-1 pr-2`\n- Implemented line clamping for descriptions (3 lines max)\n- Made status badges `flex-shrink-0` to prevent compression\n- Responsive button layouts (vertical stack on mobile, horizontal on sm+)\n- Added proper spacing between flex items\n\n#### 5. **Modal Dialogs**\n- Added responsive padding (`p-6 sm:p-8`)\n- Added max-height and scroll for mobile screens (`max-h-[90vh] overflow-y-auto`)\n- Responsive form layouts with proper spacing\n- Mobile-friendly button layouts\n\n#### 6. **Form Elements**\n- Responsive input sizing and padding (`px-3 sm:px-4`)\n- Grid layouts that stack on mobile (`grid-cols-1 sm:grid-cols-2`)\n- Mobile-friendly button sizing (`text-sm sm:text-base`)\n- Proper spacing for form elements\n\n#### 7. **CSS Utilities Added**\n- `.line-clamp-3` for text truncation\n- Mobile-specific truncation helper class\n- Custom media queries for edge cases\n\n## 📱 Testing & Verification\n\n### Breakpoints Tested:\n- **Mobile**: < 640px (sm)\n- **Tablet**: 640px - 1024px (sm - lg)\n- **Desktop**: > 1024px (lg+)\n\n### Test Page Created:\n- `test-responsive.html` - Standalone test page with sample auction data\n- Demonstrates all responsive features working correctly\n- Includes interactive elements for testing\n\n## 🔄 Changes Made\n\n### Files Modified:\n- `public/index.html` -
