/*
 * MapHero Lite — design tokens & polish layer.
 * Derived from the ui-ux-pro-max design system ("Data-Dense Dashboard"):
 *   semantic color tokens (not raw hex in components), visible focus states,
 *   150–300ms ease-out transitions, tabular figures for data, skeleton loading,
 *   44px touch targets, reduced-motion support, mobile-safe gutters.
