docker-compose.yml

# The whole stack in one command: `docker compose up --build`.
#   db       — PostgreSQL, the deployed database engine
#   backend  — the Spring app on the `demo` profile (Flyway builds the schema, seeders load demo data)
#   frontend — the built React bundle served by nginx
#
# Values come from a .env file (copy .env.example -> .env). Every one has a safe local default so a
# bare `docker compose up` works on a laptop; override them for anything real.
