# GitHub is the source of truth: every branch and tag is force-pushed to the
# mirrors. Anything committed directly on GitLab/Bitbucket/Codeberg gets
# overwritten, so merge contributions coming from there through GitHub.
# Triggered manually from the Actions tab (or `gh workflow run mirror.yaml`).
