Optimal (45–75)❌ Critical: 11px body text is too small. Increase to at least 14px.
⚠️ 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.
⚠️ Risky: Text appears on background images without overlay protection.
✅ Optimal line length: ~47 characters per line is comfortable to read.
