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

Terraform maps declarations to real-world resources via a state file (`terraform.tfstate`). In production, state is stored in remote backends (e.g. AWS S3 + DynamoDB locking) to prevent concurrent executions from corrupting infrastructure.
