   BASE — reset, typography, layout primitives, responsive grid.
   Mobile-first: base rules are the 360px layout; min-width queries at
   600 / 900 / 1200px add columns. Values come from tokens.css only.
   Components (hero, cards, CTA, FAQ…) live in components.css (docs/COMPONENTS.md);
   header, nav, footer, crisis box + WhatsApp button live in site-shell.css.
