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

    ✅ Optimal line spacing: 1.60 ratio ensures comfortable reading.

    ✅ Strong hierarchy: Headlines are 2.6x 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.

    ❌ Very long lines: ~246 chars/line causes eye strain. Use max-width: 65ch.
