Narrow lines⚠️ Small text: 15px may strain on mobile. Use ≥16px for WCAG compliance.
✅ Optimal line spacing: 1.50 ratio (ideal range 1.4–1.6).
⚠️ Partial contrast: 20 elements below WCAG AA threshold (min 1.0:1).
❌ Missing H1: Every page should have exactly one H1 element for SEO and accessibility.
✅ System fonts: Zero font loading delay — best possible LCP impact.
✅ Smart font loading: font-display: swap prevents invisible text during load (FOIT).
