Narrow lines❌ Critical: 12px body text is too small. Minimum 14px, recommend 16px+.
⚠️ Tight line spacing (1.33). Increase to 1.4–1.6 for better readability.
❌ Very complex text: Flesch score 24/100. Consider shorter sentences and simpler words.
⚠️ Partial contrast: 14 elements below WCAG AA threshold (min 1.0:1).
❌ Broken heading hierarchy: 2 level skip(s). Screen readers rely on sequential headings (h1→h2→h3).
✅ Strong hierarchy: Headlines are 3.3x larger than body text.
