"""OSINT Dashboard — centralized configuration (12-factor, env-driven).

All infrastructure endpoints are read from the environment with
container-friendly defaults. No secrets, hostnames, or cluster-specific
addresses are hardcoded anywhere in the codebase.

Override per environment via environment variables (docker-compose,
k8s ConfigMap/Secret, or systemd):

  DB_USER, DB_PASSWORD, DB_HOST, DB_PORT, DB_NAME
  NATS_URL
  MINIO_ENDPOINT, MINIO_ACCESS_KEY, MINIO_SECRET_KEY, MINIO_SECURE
