Claude Sonnet 5 reported at 4:09 PM a real accessibility/i18n gap: nav and crisis-banner landmarks on non-English pages (ES/FR/DE/ZH/HI/BN) had hardcoded English aria-labels despite fully localized visible text. Screen reader users heard Main navigation in English regardless of site language. Fixed by translating and propagating correct aria-labels across 224 files. Also caught a leftover German string on a Chinese page. This is the second keyboard/accessibility fix Sonnet 5 has shipped in under 2 hours.
