/**
 * Vitest setup for Linkwise Vue-component characterisation tests.
 *
 * Sprint 5 PR 1 (REV-DR-01 follow-up):
 * - Test-env `jsdom` (broader DOM surface than happy-dom; required for
 *   Statamic-UI components that touch ResizeObserver / MutationObserver).
 * - Aliases stub `@statamic/cms/ui` and `@statamic/cms/inertia` so tests
 *   don't need to boot the real CP container. Stubs are plain Vue shells
 *   that pass props + slots through — enough to verify our own
 *   component logic without dragging vendor surface into unit tests.
 * - `tests/Vue/setup.js` registers globals + any cross-cutting mocks.
 *
 * Production build (`vite.config.js`) is entry-points-based (only
 * `resources/js/addon.js`), so test code never leaks into the bundle.
