Geo0451/imupad ? reverse-engineered prompt

Build me a small app that turns an Android phone into a virtual Xbox 360 steering wheel for PC games.

I want a simple web page that opens on the phone, reads the phone tilt and motion, and lets me steer by holding it in landscape like a wheel. It should also have big touch controls for gas, brake, and a few extra buttons like a D pad and game actions. On the computer side, make a Python server that listens for the phone input and creates a virtual gamepad so games see it like a real controller.

Please include smoothing so the steering feels steady and does not jitter when my hands shake, but still responds quickly when I turn fast. It should work over a local connection from the phone to the PC, and let me switch between at least two different game layouts from the phone screen. If you need current setup details, look up the latest docs online.
