# Local microservices stack: one Postgres PER service (database-per-service), a
# single-broker Kafka (KRaft, no Zookeeper) for the saga, the three services, and
# the API gateway in front.
#
# Build the service images first:  ./gradlew bootJar
# Then:                            docker compose up -d
#
# Each service has its own Dockerfile that copies its build/libs/*.jar.
