# 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)
