Evaluate mobile-friendliness and propose responsive design improvements.

Your task:
1. Audit current responsive design:
   - Test at common breakpoints (mobile, tablet, desktop)
   - Check viewport meta tag
   - Evaluate touch targets (minimum 44x44px)
   - Test horizontal scrolling issues
   - Check font sizes on mobile

2. Identify issues:
   - Text too small to read
   - Content wider than screen
   - Links/buttons too close together
   - Images not responsive
   - Poor mobile navigation
   - Viewport not configured

3. Propose improvements:
   - Add/fix viewport meta tag:
     ```html
     <meta name="viewport" content="width=device-width, initial-scale=1">
     ```
   - Implement responsive images:
     ```html
     <img src="image.jpg" srcset="..." sizes="..." alt="">
     ```
   - Fix CSS for responsive layout:
     ```css
     @media (max-width: 768px) {
       /* Mobile styles */
     }
     ```

4. Mobile-specific enhancements:
   - Touch-friendly navigation
   - Hamburger menu if needed
   - Appropriate spacing
   - Readable font sizes (minimum 16px base)
   - Optimized images for mobile

5. Testing recommendations:
   - Chrome DevTools device mode
   - Real device testing
   - Mobile-Friendly Test (Google)
