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

    ✅ Optimal line spacing: 1.43 ratio ensures comfortable reading.

    ⚠️ Weak hierarchy: Headlines should be at least 2x body size for clear visual structure.

    ✅ Good performance: Using 1 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.
