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

    ✅ Optimal line spacing: 1.60 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.

    ⚠️ Cramped layout: 10 elements lack adequate spacing.
