 * A deliberately small, dependency-heavy component used for Phase 1 feasibility checks:
 * - proves `@riverbankcms/preview-next` can be imported by an external Next.js App Router host
 * - pulls in core editor dependencies so bundling/client boundary issues show up early
 *
 * This is *not* the final preview shell; it is a smoke component for the fixture app.
