Narrow lines✅ Excellent readability: 19px body text is ideal for all devices.
✅ Optimal line spacing: 1.60 ratio (ideal range 1.4–1.6).
⚠️ Partial contrast: 4 elements below WCAG AA threshold (min 1.0:1).
✅ System fonts: Zero font loading delay — best possible LCP impact.
✅ Smart font loading: font-display: swap prevents invisible text during load (FOIT).
