# Gitea Actions — the live pipeline for this repository.
#
# Gitea Actions speaks GitHub Actions syntax, so this is a near-direct port of
# .github/workflows/deploy.yml (kept as the OIDC reference in case the repo ever
# moves to GitHub or GitLab).
#
# ONE REAL DIFFERENCE: Gitea is not an AWS OIDC provider, so there is no role to
# assume. Deploys authenticate with a SCOPED IAM USER whose key lives only in
# this repository's Gitea secrets. See docs/06-deployment.md for the exact IAM
# policy — it grants four actions on one bucket and one distribution, nothing
# more. Rotate the key quarterly; OIDC would have made that unnecessary.
#
# Requires a Gitea Actions runner registered to this repo or its organisation.
