/**
 * Smoke test for the Ops Agent drawer.
 *
 * The rest of this folder tests pure logic, which is the repo's preference —
 * but "does the component actually render without throwing" is exactly the gap
 * a build cannot close, and this drawer is the only place the analysis is ever
 * seen. It needs no react-query, router or notistack provider, so it can be
 * mounted directly; there is no @testing-library in this project, so it mounts
 * through react-dom/client and reads the DOM.
 *
 * MUI renders Drawer content into a portal on document.body, so assertions read
 * body text rather than the container.
