Copy guidelines
Explain likely causes: wrong origin, expired token, or blocked preflight—users cannot see HTTP bodies blocked by CORS.
Offer a short checklist matching your support runbooks to reduce duplicate tickets.
Internationalization
Localize error titles and actions; mirror the locale of the SPA route the user is on.
Test with VoiceOver and NVDA when RTL languages change reading order.
