⚡ Ultra-Smooth Hover System with Expanding Actions

🎯 Optimized Button Layout:
- Moved checkbox to top-left corner
- Moved favorite to top-right corner
- Created expanding add button in bottom-left

🚀 Performance Enhancements:
- Reduced all animations from 200ms → 150ms
- Reduced card scaling from 105% → 102% (subtle but smooth)
- Simplified button padding and shadows
- Reduced focus ring intensity

✨ Expanding Add Button Features:
- Click to expand: Shows Collection, Deck, Own options
- Fire-themed colors: Flame orange, Gold, Wood brown
- Smooth rotation animation (45° when expanded)
- Click outside to close functionality
- Default action: Add to Collection when expanded

🎨 Fire-Themed Action Colors:
- Collection: Flame orange (var(--accent-flame))
- Deck: Golden yellow (var(--accent-gold))
- Own: Wood brown (var(--accent-wood))
- Main button: Wood → Ember when expanded

⚡ Micro-Performance Optimizations:
- Reduced button padding: p-1.5 → p-1
- Smaller shadows and hover effects
- Faster transitions across all elements
- Custom scale-102 for subtle card lift
- Optimized z-index layering

🔧 Technical Improvements:
- Self-contained ExpandingAddButton component
- Proper event propagation handling
- State management for expand/collapse
- Click-outside-to-close behavior
- Added scale-102 to Tailwind config

The cards page should now feel incredibly responsive! ⚡🔥
