/* Brikod — direction custom "3D tech", inspired by genomines.com's WebGL hero
   (own original shader + content, not their code/text/images).
   Palette: electric cyan/blue flow on near-black; paper chapters carry real
   Bujumbura photographs. Big dark sections, no icon cards, no gradients on
   text/buttons — the only "gradient-like" colour comes from the rendered
   WebGL canvas, not CSS. */
