duyet Bundle

Automated UI/UX + accessibility audit for the ClickHouse Monitor dashboard (apps/dashboard-tsr). Use this whenever the user wants to "test all pages", "audit the dashboard", "find UI/UX issues", "check accessibility / a11y", "spot visual regressions", "screenshot every route", "reproduce a UI bug", or asks to verify the dashboard UI after a change or deploy. It sweeps every dashboard route headlessly, captures console errors + failed network calls, runs axe-core accessibility scans, detects layout overflow and stuck loading skeletons, diffs screenshots against a baseline for visual regression, and emits a runnable repro (trace.zip + script) for each issue so it can be replayed on demand. Runs against the local dev server (auth bypassed) by default, or the live Clerk-protected deployment using the stored test session. Prefer this over ad-hoc one-off Playwright scripts for any multi-page UI check.
