/* ============================================================
   ARC CIEL AFRICA — Design tokens
   Concept: the brand's own mark — a topographic contour map of
   the African continent in teal-to-gold — becomes the organizing
   visual motif (contour lines, elevation bands, survey-grade
   coordinates) in place of a generic HUD. Colors are lifted
   directly from existing Arc Ciel Africa collateral.
