❌ Critical: 12px body text is too small. Increase to at least 14px.

✅ Optimal line spacing: 1.50 ratio ensures comfortable reading.

✅ Good performance: Using 1 font families keeps load times fast.

✅ Consistent design: Single font family with weight variations is a modern best practice.

✅ Optimal line length: ~54 characters per line is comfortable to read.

⚠️ Cramped layout: 53 elements lack adequate spacing.
