#   web      Next 16 sandbox                → http://localhost:3000
#   relay    Go SSE daemon (live ticks)     → http://localhost:7331
#   agents   Python FastAPI crowd marshals  → http://localhost:7332
#
# Every variable these services read is optional — the simulation is fully
# offline and deterministic with bare defaults. `.env.example` is committed and
# key-free, so compose can mount it directly; copy it to `.env` if you want
# private local overrides:
#
#   cp .env.example .env   (and change `env_file:` entries to point there)
#
# No volumes or databases are needed: stateless by construction.
