on YouTube ↗32m

" summary

Lighthouse surfaces low‑hanging accessibility failures but DevTools reveal the real bugs: the accessibility tree shows which nodes are ignored, the ARIA name/role/state values expose wrong labels and missing descriptions, the color‑blindness emulation and reduced‑motion toggles reproduce vision and motion issues, forced‑state inspection finds removed focus rings, and a document.activeElement watcher confirms keyboard focus order — concrete checks that find missing alt text, incorrect ARIA, and broken keyboard navigation.
