/* ==========================================================================
   PRODUIT — composants des 3 pages produit dediees (energy-pouch,
   energy-shot, creatine-gummies). Repris fidelement de la structure de la
   maquette du boss (fuel-power-site f.html) : ptabs, hero--premium, galerie
   + cartes de format (.gal/.tiers), bandeau (.band), 4 raisons (.grid4/.ben),
   avis (.rev__card), science/posologie (.split/.data/.claim), FAQ (.faq).

   Seule difference volontaire avec la maquette : les couleurs sont prises
   dans le design system existant (var(--lime), var(--card), var(--ligne),
   var(--disp), var(--util)...) au lieu des variables --acc/--line/--display
   de la maquette, pour suivre automatiquement la couleur tonique de chaque
   page (voir body[data-tone] dans css/base.css) sans dupliquer de palette.
