/* =========================================================
   AFENHOR — Design System
   Palette drawn from the Great Lakes region: night-indigo skies,
   sun-baked ochre earth, and the deep clay red of worked soil.
   Signature motif: an interlaced weave pattern (raffia / kuba-cloth
   logic — many threads holding together) used as a structural device,
   never as flat decoration.
