AI translates the explanation and quiz text while preserving code and answer scoring.

ConfigMaps inject non-confidential key-value configs as environment variables or mounted files. Secrets store base64-encoded sensitive keys (ideally encrypted at rest via KMS). PersistentVolumeClaims (PVCs) dynamically request storage from Container Storage Interface (CSI) drivers.
