  # HEADS UP! this "nightly" job will only ever run on the `main` branch due to
  # it being a cron job, and the last commit on main will be what github shows
  # as the trigger however in the checkout below we specify the `dev` branch,
  # so all the scripts in this job will be ran from that, confusing i know, so
  # in some cases we'll need to create multiple PRs when modifying nightly
