Your question is Two-Node Bouncing Ball Server-Client. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you build a server that simulates and displays a 2D bouncing ball, sends each frame to a client, estimates ball position with computer vision, returns position data to compute error, and deploys with Docker and Kubernetes with a comprehensive test suite?
