```

style(global): update background gradients and visual styling

- Replace radial gradient with combined radial and linear gradients
- Update color schemes with warmer tones and improved transparency
- Adjust border colors and add subtle glow effects
- Increase blur intensity for better glassmorphism effect

style(game): enhance seat player card design

- Add avatar panel container for better layout structure
- Implement dealer mark positioning with absolute placement
- Add missing suit icons with computed property mapping
- Replace text-based missing marks with image icons when available
- Improve visual hierarchy and spacing between elements

refactor(game): add computed property for dynamic suit icon selection

- Import suit icon assets (wan, tong, tiao)
- Create computed property to map suit labels to corresponding icons
- Handle fallback to text display when no icon is available
