Redesigned the entire frontend with a new "DECK" aesthetic:
- 5 distinctive themes: Midnight, Daylight, Neon, Vapor, Matrix
- Compact pill-shaped sound buttons with category color bars
- Tab navigation: All Sounds / Favorites / Recently Added
- Horizontal category filter chips with color coding
- Fixed bottom control bar: Stop, Random, Party, Volume
- Responsive layout optimized for 800+ sounds
- Syne + Outfit typography pairing
- Party mode with animated gradient effects
- Search with clear button, "Now Playing" indicator
- Admin panel as modal overlay
- Subtle dot grid background pattern on dark themes
Replaces the previous Apple Music-style card layout with a dense,
efficient grid that scales properly for large sound libraries.
