/* =============================================================================
   EV Referral Atlas — design system  (ATLAS / COUNTRY-DIRECTORY archetype)
   Distinct identity vs siblings:
     · Condensed / grotesque headings (no serif), UPPERCASE tracked overlines.
     · Cool violet / aubergine palette (never warm cream).
     · Dense reference/atlas grid of country tiles, hairline dividers, compact rows.
     · The code lives in a persistent DARK TOP UTILITY BAR (.codebar), not a card.
     · A sticky horizontal country switcher (.geoswitch) reinforces the index feel.
   System-available fonts only → no font fetch, no CLS. Light + dark via media query.
   All bespoke class names — deliberately share nothing with the sibling sites.
