- Added localization support for Swedish and English languages. - Integrated localized strings for user messages in the API error mapper. - Updated UI components to use localized strings for labels and messages. - Ensured all error messages are context-aware and utilize the localization framework. - Created regression test to prevent common ASCII fallbacks in Swedish UI text.
