/**
 * Radix overlay regression tests -- MEDIUM tier.
 *
 * Guards the bug class fixed by de-duping `@radix-ui/react-dismissable-layer`:
 *
 *   1. Body `pointer-events: none` getting stuck after nested overlays close
 *   2. Dropdown typeahead breaking on the second open
 *   3. Tooltips popping after a dropdown closes (focus restore side-effect)
 *
 * These tests are grouped by UI path rather than by symptom, since a given
 * flow usually exercises more than one failure mode.
 *
 * TODO: migrate these tests into the corresponding page specs
 * (face-library.spec.ts, system.spec.ts, review.spec.ts) when those files
 * come out of PENDING_REWRITE in e2e/scripts/lint-specs.mjs. They live in
 * a dedicated file today so they stay lint-compliant (no waitForTimeout,
 * no conditional isVisible) while the page specs are still exempt.
