name: Terraform Terragrunt (contour)

# One workflow for ALL closed contours. Per-contour differentiation is done via
# repository variables/secrets in each contour's Gitea — this is the downstream
# runner contract:
#   vars:    INFRA_ENV, RUNNER_LABEL, RUNNER_IMAGE
#   secrets: TF_STATE_S3_ENDPOINT, TF_STATE_S3_BUCKET, S3_ACCESS_KEY, S3_SECRET_KEY,
#            VAULT_ADDR, VAULT_TOKEN, SOPS_AGE_KEY, KUBECONFIG_B64 (external runner
#            only), KUBE_CONTEXT (external runner only)
# Infra-service admin creds are NOT passed as secrets — they are read from Vault
# at run time (see the "Run ... stacks" step) so the single source of truth stays
# in the contour Vault.
