# Full-stack dev/run orchestration for temetro.
#
#   docker compose up      # db + backend + frontend — that's it.
#
# No .env or secret setup is required: the backend generates any missing
# secrets on first start and persists them (see docker-entrypoint.sh). Create a
# .env only if you want to override something (SMTP, a real auth secret, etc.).
#
# Frontend  -> http://localhost:3000
# Backend   -> http://localhost:4000
# Postgres  -> localhost:5432
#
# The frontend service builds the sibling ../frontend app. Run just the API
# with:  docker compose up db backend
#
# Optional DB browser (Adminer) lives behind a profile:
#   docker compose --profile tools up adminer   # http://localhost:8080
