      # Built through the image stage rather than the checkout, because the
      # stage copies ui/litellm-dashboard/ alone: an import reaching above the
      # dashboard root resolves in a checkout and fails in every image we ship.
      # Dockerfile, docker/Dockerfile.non_root and ui/Dockerfile share this
      # stage verbatim, so building one covers all three.
