  // NOTE: We exclude Storybook stories and test utilities which import
  // Storybook and its dependencies, because:
  //   a) we don't want Storybook types in our build output, and
  //   b) we don't want transitive dependencies, like @emotion/core, to have
  //      their React interface augmentations in our build output.
