DarwinsBuddy/foosball-ai — reverse-engineered prompt

Build me a Python computer vision tool for a foosball table. I want to point a webcam at a match, or load a recorded video, and have the app find the play area, follow the ball, show its trail, and automatically update the score when a goal happens on either side. It should have a simple live view that draws the table area, the ball position, recent path, goal zones, and current score, but it should also be able to run without showing a window.

Please include setup and run commands, sensible config files for camera calibration, ball color calibration, and goal detection, plus a way to calibrate the ball color from a sample video. If a goal is detected, let it optionally play a sound or call a webhook so another scoreboard can react. Support both webcam input and video file input. Use Python and OpenCV, and look up current docs online if needed.
