The Tailwind v4 @theme block defines --color-danger as the semantic error
token, and 15+ files across the codebase use text-danger consistently.
SettingsPage was the lone outlier with five text-error / border-error
sites (audio devices, profile delete, vocabulary, term delete, diagnostic
report). Without a --color-error token, those utilities resolved to the
default text colour, so error messages rendered in warm cream instead of
red. Verified live via Playwright probe before and after.
