Build me a simple Outrun style racing game in the browser with a fake 3D road effect, moving scenery, curves, hills, and a final playable version with road, car movement, speed, and basic collisions.

I want it to feel like a classic arcade racer, with colorful retro visuals, background music, and a sense of speed. If it helps, start with a very basic straight road version first, then add curves, hills, and the full game so I can see it come together step by step.

Keep it all in one easy to run HTML page or a small set of browser files, and make sure it works smoothly in modern browsers. If you need to look up current docs or best practices online, go ahead.
