❌ Critical: 12px body text is too small. Increase to at least 14px.

⚠️ Tight line spacing (1.00). Consider 1.4-1.6 for better readability.

✅ Strong hierarchy: Headlines are 4.0x larger than body text.

✅ Smart font loading: Using font-display: swap prevents invisible text during load.

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

❌ Very long lines: ~207 chars/line causes eye strain. Use max-width: 65ch.
