Add unified UI component library
Create reusable cloud-themed components:
- Card: cloud-styled containers with variants (default, large, compact)
- Button: primary, secondary, ghost variants with hover effects
- Input: form inputs with focus states
- Badge: status badges (success, warning, danger, info)
- StatusGlow: glowing status indicators for player states
- Modal: cloud-styled modal overlays
All components follow the 0.6s ease transition pattern and integrate
with existing design tokens for consistent cloud aesthetic.
