  # these tests never touch CUDA. GPU integration tests belong in a
  # separate job that requires a self-hosted GPU runner.
  #
  # NOTE: tests/unit/ must NOT import from the package root __init__.py
  # directly (that triggers folder_paths / server imports). All ComfyUI
  # integration tests belong in tests/integration/ (not run here).
