    ✅ Excellent readability: 17px body text is ideal for all devices.

    ✅ Strong hierarchy: Headlines are 3.5x 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.

    ⚠️ Risky: Text appears on background images without overlay protection.

    ⚠️ Cramped layout: 35 elements lack adequate spacing.
