AaryaG-17/GestureOS ? reverse-engineered prompt

Build me a Python app that lets me control my computer with hand gestures from a webcam.

I want real time hand tracking with OpenCV and MediaPipe, and a clean setup where gesture detection is separate from the desktop actions it triggers. It should already support an upside down L gesture for volume control and a sideways open hand gesture for brightness control, and it should be easy to add more gestures later without rewriting the whole thing.

Please make it feel modular and organized, with separate pieces for core logic, gestures, actions, models, and utilities. It should support both hands, avoid gesture conflicts as much as possible, and be built in a way that makes future features like screenshot capture, virtual mouse control, window management, media controls, clipboard tools, and custom gesture mapping easy to add.

If you need current docs for MediaPipe or OpenCV, look them up online while you work.
