server.py serves the repo root rather than web/, so the 2D prototype stays reachable next to the 3D port — you want to flip between the reference implementation and the thing you're porting without stopping the server. --selfcheck verifies the tree and prints URLs; no node, no network. three r175 is copied in from 90sDJsim rather than referenced, so the game has no runtime dependency on a sibling checkout.
