+# CI on the self-hosted Gitea, ported from .gitlab-ci.yml during the move off
+# GitLab (2026-09-22). Gitea reads .gitea/workflows and ignores .github/ once
+# this directory exists; .github/workflows stays as it was for GitHub.
+#
+# Every job runs in an image pinned by digest (tag in the trailing comment),
+# and the only action used is coffey-labs/actions/checkout pinned by SHA. The
+# instance resolves short `uses:` against itself, never GitHub, so nothing
+# unreviewed can be pulled in.
+#
+# Not ported, as on GitLab: publish.yml and release.yml still need doing.
