# The whole app in containers, production-shaped: `docker compose up --build`, then http://localhost:3000.
# Same image as the deploy (Dockerfile), Postgres, migrations on boot (bin/docker-entrypoint).
# Day-to-day development is `bin/dev` (native, SQLite, fast rebuilds); this is "does it run like prod?".
#
#   docker compose up --build                     app + Postgres
#   docker compose up -d db                       only Postgres, for `TEST_DATABASE_URL=… cargo nextest run`
#   docker compose down -v                        stop and delete the database volume
#
# Ports are overridable: APP_PORT (3000), DB_PORT (5432).
