#   cp .env.v2.example .env.v2
#   docker compose -f docker-compose.v2.yml --env-file .env.v2 up -d
#
# Public port:  8080  → API Gateway
# MinIO UI:     9001  → http://localhost:9001
#
# Per-service ports are intentionally NOT published (internal Docker network).
# Add `ports: ["5010:8080"]` to a service to expose it for local debugging.
