# Production Compose stack — one file for every stage and for self-hosters.
# Configuration comes from .env (see .env.example); the host reverse proxy
# routes to the two published localhost ports (deployment.md §Compose).
#
# Networks: `frontend` is what the reverse proxy reaches (via published
# ports); `internal` connects api/collab to db and (later) the converter
# sidecars, which are never exposed.
