# Local dev + smoke-test stack.
#
# Default profile starts the database and cache only — bring your own app
# (run `just dev` against these services). Use the `app` profile to also
# spin up nagara itself in a container.
#
# Usage:
#   docker compose up -d              # postgres + redis only
#   docker compose --profile app up   # add the app container
