Localization & Internationalization Testing

<default_to_action> When testing multi-language/region support:

1. VERIFY translation coverage (all strings translated)
2. TEST locale-specific formats (date, time, currency, numbers)
3. VALIDATE RTL layout (Arabic, Hebrew)
4. CHECK character encoding (UTF-8, unicode)
5. CONFIRM cultural appropriateness (icons, colors, content)

Quick i18n Checklist:

• All user-facing strings externalized
• No hardcoded text in code
• Date/time/currency formatted per locale
• RTL languages flip layout correctly
• Unicode characters display properly
