Needs attention✅ Excellent readability: 24px body text is ideal for all devices.
✅ Strong hierarchy: Headlines are 2.7x larger than body text.
✅ 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.
⚠️ Risky: Text appears on background images without overlay protection.
