# Base compose stack. Uses ${VAR:-default} interpolation throughout so the
# stack boots with zero config — sane dev defaults baked in. For production
# deployments, override the defaults via shell env vars or a .env file:
#
#     DB_PASSWORD=...real... SECRET_KEY=...real... docker compose up
#
# The dev override (docker-compose.override.yml) is auto-merged when you
# run `docker compose up` from this directory and switches images to
# local builds + DEBUG logging.
