- * This story tests the real AlertApi integration.
- * It uses the alertApi from the TestApiProvider (set up in storybook preview)
- * and shows how alerts posted via alertApi.post() appear.
- *
- * Note: The storybook preview.tsx renders AlertDisplay from core-components,
- * which still uses Material UI. To test the new ToastDisplay, run the actual
- * Backstage app where the app plugin's elements.tsx is used.
