 ## Optional: Headlamp OIDC and SAML
 
 Headlamp in your GitOps repo consumes **Cognito** as OIDC issuer; this Terraform creates Cognito, wires **EKS `aws_eks_identity_provider_config`** (`username_claim = sub`, `groups_claim = cognito:groups`), and writes **`headlamp/oidc`** to Secrets Manager for the in-cluster sync.
