/* ============================================================================
   HUITZ — CARTOON KAWAII B (standard FACETA) — table de cartes cyan/or
   ============================================================================
   Sticker kawaii : aplats + contours nets, ombres PLATES zéro flou (aucun
   `backdrop-filter`/`filter:blur`), formes rondes, reflet `--kawaii-sheen`
   statique (jamais de sheen animé). Thème clair/sombre piloté par
   `html[data-theme]` (/_kit/theme.js, choix explicite du hub — plus l'OS
   seul). Identité conservée : table cyan/nuit, accent or, rouge cartes.
