Audit and fix interaction quality — a11y, focus, forms, touch targets, semantics, motion preferences. Use only when the task is an a11y/guidelines pass or form/dialog interaction fix. Prefer quality-check when the goal is ship/verify/regression; prefer product-design when multi-step product UX craft is unclear; frontend-design for full FE builds. Not for visual brand redesign, React performance alone (react-performance), or Playwright/e2e proof loops (browser-verify).
