    ✅ Excellent readability: 19px 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).

    ⚠️ Cramped layout: 22 elements lack adequate spacing.

    ✅ Clean layout: Consistent left alignment throughout.
