Needs attention✅ Excellent readability: 24px body text is ideal for all devices.
⚠️ Weak hierarchy: Headlines should be at least 2x body size for clear visual structure.
✅ Excellent performance: System fonts eliminate font loading delays (better LCP).
✅ Consistent design: Single font family with weight variations is a modern best practice.
✅ Smart font loading: Using font-display: swap prevents invisible text during load.
⚠️ Wide lines: ~102 chars/line. Consider max-width for better reading flow.
