Title: Neon Tunnel Racer

Create a 3D synth tunnel racer with glowing rings, three lanes, prism gates, a visible player craft, boost, combo, score distance, and shield state. It should be readable in motion and strong enough for a homepage preview or short video capture.

Gameplay requirements:
- The player moves left/right across three lanes and uses boost.
- Obstacles and bonus prisms move toward the player and alter shield/combo.
- HUD shows distance, shield, combo, and speed.
- Controls visibly change state: lane buttons/keys, boost button/space, restart.
- Success state: clear 600 meters; failure state: shield depletion.

Acceptance gates:
- Not a static tunnel render; controls and collisions must affect state.
- Real 3D browser rendering with visible tunnel depth.
- First frame must communicate speed, lanes, obstacles, and playable objective.
- No remote textures, models, backend APIs, or production provider calls.
