⚠️ Small text: 14px may be hard to read on mobile. Consider 16px+.

⚠️ Tight line spacing (1.10). Consider 1.4-1.6 for better readability.

✅ Good performance: Using 2 font families keeps load times fast.

✅ 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.

⚠️ Cramped layout: 200 elements lack adequate spacing.
