Sousannah/hand-tracking-using-mediapipe ? reverse-engineered prompt

Build me a simple Python app that uses my webcam to track hands in real time with MediaPipe and OpenCV.

I want it to open a camera window, detect hand landmarks, draw the finger points and connections on top of the video, and show the current FPS on screen. It should keep running smoothly until I press q to quit. Please make it easy to run from the command line, with clear setup steps for the needed Python packages, and keep the code straightforward so I can understand or tweak it later.

If anything needs a newer version of the libraries, look up the current docs online and use the right approach. Also make sure the output looks clean and similar to a basic hand tracking demo.
