# In principle, we'd want to only run CI on meaningful changes; e.g., don't run
# CI if the only thing we change is `CHANGELOG.md` or if we push to a side
# branch. We could do this by filtering on branch (master) and on files
# (excluding **.md files). However, runs that get filtered never return
# successful status (blocking merging if the check is required). See:
# https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#example-including-paths
# There is a solution if this type of optimization is preferred. See:
# https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/troubleshooting-required-status-checks#handling-skipped-but-required-checks
