| # Lightweight image — no CityFlow C++ build, no torch. | |
| # All simulation runs are delegated to Space 1 (OpenEnv API) via HTTP. | |
| # | |
| # HF Spaces expects the app to listen on port 7860. | |
| # | |
| # Required env vars (set in the Space settings or README front matter): | |
| # OPENENV_API_URL URL of the OpenEnv API Space | |
| # e.g. https://your-org-openenv-api.hf.space | |
| # | |
| # Optional: | |
| # DATA_DIR city config root for roadnet matching (default: /app/data/bundled) | |
| # REPLAY_ROOT where replays are cached on disk (default: /app/results/replays) | |
