riyanshibariyaa/OpenCV-Based-Real-time-Employee-Tracking-System ? reverse-engineered prompt

Build me a web app that tracks whether an employee is present at their desk in real time using computer vision.

I want a clean dashboard where I can start tracking from a webcam, uploaded video, or a video stream, then watch the feed with boxes and status overlays showing when a person is detected inside or outside the work area. It should let me adjust things like detection confidence, absence timeout, and whether the desk area is auto detected or set manually. I also want a live status panel, simple logs with timestamps, and a way to review basic activity history.

Make it feel modern and easy to use, with a dark themed responsive interface. Use OpenCV and YOLO for the detection, Flask for the backend, and make it work locally and in Docker. If you need current docs or setup details, look them up online and keep the implementation practical.
