# Ported from .github/workflows/ci.yml for Forgejo Actions.
# Differences from the GitHub version:
#   - no `merge_group` trigger (Forgejo has no merge queue)
#   - gitleaks action referenced by full GitHub URL (custom action, not on
#     the Forgejo actions mirror)
#   - the visual-diff PR comment posts via the Forgejo API instead of `gh`
# The `ci/forgejo-actions` push branch is temporary (lets this branch re-run
# CI pre-merge); drop it once merged to main.
