Provide expert advice on font selection and implementation, focusing on typography hierarchy.

Your task:
1. Analyze current font usage in the project:
   - Current font families
   - Font hierarchy (headings, body, etc.)
   - Font stacking
   - Web font loading

2. Provide font recommendations:
   - Suggest fonts from Google Font Library or web-safe fonts
   - Consider readability and brand alignment
   - Recommend font pairings (heading + body)
   - Suggest fallback fonts

3. Implement better font hierarchy:
   ```css
   /* Example hierarchy */
   h1 { font-family: 'Heading Font', fallback; font-size: 2.5rem; }
   h2 { font-family: 'Heading Font', fallback; font-size: 2rem; }
   body { font-family: 'Body Font', fallback; font-size: 1rem; }
   ```

4. Optimize font loading:
   - Use font-display property
   - Preload critical fonts
   - Implement proper font stacking
   - Consider variable fonts for performance

5. Enhance visual appeal:
   - Set appropriate line-height
   - Configure letter-spacing
   - Establish font-weight hierarchy
   - Ensure responsive typography
