/* ==========================================================================
   NZOTO — design tokens
   Purpose : single source of truth for every colour, size, radius, shadow,
             duration and layer used by base/components/layout/utilities.css.
   Rule    : component styles never contain raw hex or px values — only var().
             (Media-query breakpoints are the one exception: CSS cannot read
             custom properties there. They are listed at the end of this file.)
   Rebrand : change the five --brand-* values below. Everything else derives.
             Admin › Settings can override --brand-primary / --brand-accent at
             runtime (see app.js › applyThemeSettings).
