# Layered on top of docker-compose.yml, never used alone. The installer writes
# this into .env when asked to build from source:
#
#   COMPOSE_FILE=docker-compose.yml:docker-compose.build.yml
#
# Compose reads COMPOSE_FILE from .env itself, so every documented command
# stays a plain `docker compose up -d` with no extra flags to remember.

# Costs a build on the operator's own server, which needs roughly two
# gigabytes of memory and several minutes. That is exactly what publishing
# images removed, so this exists for people who self-host in order to compile
# it themselves, not as the normal path.
