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

    ✅ Strong hierarchy: Headlines are 2.7x larger than body text.

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

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

    ✅ Protected text on images: Using text-shadow for readability.

    ✅ Optimal line length: ~57 characters per line is comfortable to read.
