Web quality audit

Comprehensive quality review that combines live browser evidence with source inspection. Covers Performance, Accessibility, SEO, Best Practices, and Agentic Browsing without treating an aggregate score as proof of quality.

Lighthouse 13+. The Performance category now uses shared Performance Insights across Lighthouse and the DevTools Performance panel (announcement). Follow current insight names and evidence. Do not require removed audit IDs or automatically recreate their recommendations; some were retired because they were noisy, inactionable, or easy to over-recommend.
