SPLATPLAYS/Tron ? reverse-engineered prompt

Build me a simple browser game based on Tron that I can open in the browser and play right away.

I want a clean neon style game with the classic light cycle feel, where I can control a bike or snake like trail, move around a grid, and avoid crashing into walls or trails. It should have a start screen, a score counter, game over when I lose, and an easy way to restart. If it makes sense, add single player against a basic computer opponent or just a second player option, but keep it fun and straightforward.

Please wire it up so it runs from the existing project setup, and use the server if needed for launching or serving the page. Make it look polished with simple arcade visuals and smooth controls, and keep the code easy to understand. If you need to check anything current online, go ahead and look up the best way to do it.
