# MinIO — Ephemeral object storage for integration tests
# Namespace is substituted at runtime via envsubst
# No persistence — uses emptyDir
# Credentials: minioadmin/minioadmin (hardcoded for ephemeral sandbox)
# Includes a Job that waits for MinIO readiness and creates the stonks-normalized bucket
