/* ==========================================================================
   COLORZ — style kawaii B (DÉCISION porteur C6 : contour épais net, aplat +
   une ombre plate, reflet brillant, formes rondes). Remplace le premium
   glassmorphism/glow : zéro backdrop-filter, zéro glow multi-couche,
   surfaces opaques, contour d'encre, ombre plate décalée (jamais de flou).
   Thème piloté par le hub (html[data-theme], voir /_kit/theme.js) plutôt
   que l'OS seul. Identité Colorz conservée : violet doux + accents pastel,
   ambiance "atelier de coloriage" plutôt que "jeu d'arcade".
