Created a 3D surfing game at `public/surf-3d.html` with:

- **3D Graphics**: Full Three.js rendering with realistic lighting and shadows
- **Dynamic Ocean**: Procedurally animated water with multiple wave systems
- **Physics**: Realistic surfing physics with air time, speed, and wave interaction
- **Controls**: WASD/Arrows to move, Space to jump, Q/E to spin, Shift to boost
- **Scoring**: Points for tricks, air time, speed, and combos
- **Visual Effects**: Particle spray, shadows, fog, and gradient sky

The game features proper 3D wave geometry that the surfer can ride, jump off, and perform tricks on.
