/* Anas Design System · v7.1 — Tokens + Primitives
 *
 * Mirror of packages/ui/src/tokens.ts. Single source of truth for the landing
 * site. v6.4.0 (2026-06-09): migrated off v2 t-shirt token names to the canonical
 * scales — spacing --sp-N, radii --rad-N, type --ft-NN, motion --t-N; committee
 * chat tokens own their role; +info; derived button states; dropped the banned
 * concierge chat token, the off-scale 30px radius, and the snug/label line-heights;
 * fixed the cookie-banner undefined-border bug.
 * v7.1 (2026-07-05): +--brand-ink — brand-colored text on brand tint/wash surfaces.
