/**
 * Loop 10 — Dialog + Sheet primitive coverage.
 *
 * Pins the Radix-backed contract the rest of the loop builds on:
 *   - `role="dialog"` + `aria-modal="true"` on open
 *   - Escape closes
 *   - Click on overlay closes
 *   - Built-in DialogClose closes
 *   - Sheet renders per-side data-side attribute (drives the slide
 *     animation in globals.css)
 *
 * Focus-trap behaviour (tab cycling inside) is intentionally NOT
 * asserted here — happy-dom doesn't simulate focus-trap semantics,
 * and Radix's own test suite covers them. The Playwright e2e suite
 * and the axe-core CI gate cover real-browser behaviour.
