Implemented comprehensive internationalization (i18n) for both frontend and backend: Frontend: - Added react-i18next configuration with Spanish (default) and English - Created translation files (locales/es.json, locales/en.json) - Refactored core components to use i18n: LoginPage, DashboardHeader, DataUploader - Created LanguageSelector component with toggle between ES/EN - Updated API client to send Accept-Language header Backend: - Created i18n module with translation dictionary for error messages - Updated security.py to return localized authentication errors - Updated api/analysis.py to return localized validation errors - Implemented language detection from Accept-Language header Spanish remains the default language ensuring backward compatibility. Users can switch between languages using the language selector in the dashboard header. https://claude.ai/code/session_1N9VX
