Narrow lines⚠️ Small text: 16px may strain on mobile. Use ≥16px for WCAG compliance.
⚠️ Wide line spacing (2.00). 1.4–1.6 is optimal for body text.
⚠️ Partial contrast: 8 elements below WCAG AA threshold (min 2.7:1).
✅ Perfect heading hierarchy: Sequential h1→h2→h3 with single H1 — ideal for SEO & accessibility.
✅ Strong hierarchy: Headlines are 2.2x larger than body text.
✅ System fonts: Zero font loading delay — best possible LCP impact.
