/* ==========================================================
   TJFI — feuille de style unique · v5 « Lumière froide »
   Même chambre optique que « Dispersion », épurée : plus de
   spectre, un seul phénomène — la lumière blanche dans un
   camaïeu de bleus. Le prisme 3D demeure, les halos suivent
   le pointeur, mais chaque transition n'engage jamais plus
   de deux couleurs : blanc vers bleu, bleu vers bleu.
   Aucune police externe, aucun script tiers, aucun cookie.
