      # fail-fast if set to 'true' here is good for production, but when
      # debugging, set to 'false'. fail-fast means if *any* ci test in the matrix fails
      # GitHub Actions will stop any other test immediately. So good for production, bad
      # when trying to figure something out. For more info see:
