⚠️ Small text: 15px may be hard to read on mobile. Consider 16px+.

✅ Strong hierarchy: Headlines are 2.9x larger than body text.

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

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

⚠️ Cramped layout: 10 elements lack adequate spacing.
