jayesh-cmd/virtual-keyboard ? reverse-engineered prompt

Build me a touchless virtual keyboard and air mouse app in Python that uses my webcam to track both hands in real time.

I want my left hand to move the mouse cursor smoothly, with a little jitter smoothing so it feels stable, and a thumb plus index finger pinch should act like a left click. If I keep holding the pinch, it should let me drag things around or highlight text. My right hand should control an on screen virtual keyboard, and pinching on a key should type that character into whatever app I’m using, even if this app is just running in the background.

Please make it look clean and futuristic, with a nice translucent keyboard on screen, and open the camera window large enough to use comfortably. Use Python, OpenCV, and MediaPipe, and if you need to check current docs or best practices, look them up online.
