+      PHASE 2.1 IMPLEMENTATION COMPLETED - i18n & Dark Mode
+      
+      ✅ IMPLEMENTED:
+      1. Language Settings (i18n):
+         - Silent language switching (no alerts, no navigation reset)
+         - 6 languages fully configured
+         - AsyncStorage persistence
+         - Backend sync (fire-and-forget)
+         - Theme-aware UI
+      
+      2. Dark Mode:
+         - Fully functional toggle in Settings
+         - Theme persists across app restarts
+         - Dynamic StatusBar (light/dark)
+         - Applied to Settings and LanguageSettings screens
+      
+      📦 NEW FILES:
+      - /app/frontend/src/config/i18n.ts
+      - /app/frontend/src/contexts/ThemeContext.tsx
+      
+      🔧 UPDATED FILES:
+      - /app/frontend/App.tsx (ThemeProvider integration)
+      - /app/frontend/src/screens/SettingsScreen.tsx (dark mode toggle + theme colors)
+      - /app/frontend/src/screens/LanguageSettingsScreen.tsx (silent switching + theme colors)
+      
+      Ready for frontend testing to verify:
+      - Language switching without navigation reset
+      - Dark mode toggle functionality
+      - Theme persistence
+      - UI color adaptation
