      # I could have only added the turbo-ignore without specifying the sha to the last
      # commit of the base branch but that would make the turbo compare with the parent
      # commit of the branch. This would make the CI fail when the dev makes
      # a change that affects the design-system in the first commit and pass
      # when the dev makes a change that DOES NOT affect the design-system in the second
      # commit of the PR.
      # We prevent this by comparing the base branch with the head branch.
