Modern UI Improvements

Converted to Next.js with TypeScript for better development experience

Enhanced chat interface with smooth animations and better spacing

Improved loading states with animated spinners and typing indicators

Better responsive design that works on all screen sizes

Glassmorphism design with backdrop blur effects for a premium feel

Key Features Maintained

✅ Pi Network SDK integration with exact initialization sequence

✅ Authentication overlay with proper error handling

✅ Backend communication with chat API

✅ Real-time messaging with typing indicators

✅ All essential authentication logging preserved

✅ Proper error handling throughout the authentication flow

The background now features a beautiful purple-to-blue gradient that creates a more engaging and modern appearance while maintaining all the critical Pi Network functionality you specified. The app will authenticate users through Pi Network before allowing them to use the chat functionality, exactly as in your original code.
