    ✅ Excellent readability: 20px body text is ideal for all devices.

    ✅ Optimal line spacing: 1.80 ratio ensures comfortable reading.

    ✅ Strong hierarchy: Headlines are 2.5x larger than body text.

    ✅ 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.
