  # DO NOT run on push: but only on Pull Requests
  # As this repository is configured to enforce "never push directly to main"
  # (it would say: [remote rejected] main -> main (protected branch hook declined)),
  # there doesn't seem to be a point to re-run Mega Linter after PRs are merged.
  # One reason to change this could be to configure this to let it raise PRs to
  # apply fixes to main, but the overall workflow for that isn't very clear
  # to me yet, because PRs would still be red, so... ?
