    ✅ Excellent readability: 29px body text is ideal for all devices.

    ⚠️ Weak hierarchy: Headlines should be at least 2x body size for clear visual structure.

    ✅ Excellent performance: System fonts eliminate font loading delays (better LCP).

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

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

    ⚠️ Cramped layout: 6 elements lack adequate spacing.
