 Multi-node Stirling is UP.

   App (via load balancer): http://localhost:8080     (admin / stirling)
   MinIO console:           http://localhost:9001     (minioadmin / minioadmin)
   Postgres:                localhost:5434            (stirling / stirling, db 'stirling')

   Seeded users:            user01..user40@stirling.test / Password123!
   Global API key:          multinode-test-key   (header: X-API-KEY)

 Try it:
   ./validate-multinode-test.sh        # multi-node smoke tests (optional)
   $COMPOSE logs -f stirling-1         # tail a node
   ./start-multinode-test.sh --down    # stop + wipe

 Nodes are reachable directly for cross-node checks:
   docker compose -f docker-compose-multinode.yml exec stirling-1 curl -s localhost:8080/api/v1/info/status
