/* ========================================
   CSS VARIABLES - V3.3.1 VISUAL SYSTEM
   ========================================

   UNITES : px uniquement, jamais rem. Le theme Mitxoda (blogbyte/magbyte)
   fixe `html { font-size: 10px }`. Cette feuille ayant ete ecrite pour la
   base navigateur de 16px, chaque `rem` ne rendait que 62,5% de la taille
   voulue : les libelles annonces a 18px sortaient a 11,25px, les aides a
   16px sortaient a 10px, et tous les espacements etaient tasses d'autant.
   Les 300 valeurs en rem ont ete converties en px (x16) le 2026-08-19 ; les
   commentaires de ce bloc, qui donnaient deja les px voulus, servent de
   reference et concordent exactement. Meme regle que assets/css/
   tsf-form-mobile.css. Ne pas reintroduire de rem ici.
