/* CHIFRZ — passe kawaii sticker (standard FACETA, cf BACKLOG.md §PIVOT DESIGN /
   §PROGRAMME AUTONOME, vague 3 : 9/66, suite alphabétique après `chesz`).
   Contour épais net, aplats + une seule ombre plate (zéro flou), reflet kawaii
   en 2e couche de `background`. Remplace le glassmorphism premium (27
   `backdrop-filter`, glows flous `rgba(212,175,55,X)`) — ce fichier consomme
   surtout les tokens PARTAGÉS `--cb-glass-*`/`--cb-overlay-blur`/`--cb-shadow-*`
   (contrairement à d'autres jeux déjà passés qui les avaient dupliqués en
   local) : ils sont donc redéfinis ICI, en override LOCAL (ce fichier charge
   après /_kit/kit-design.css), même patron que konekt/gomz/colorz — zéro
   impact sur le reste de la flotte. Identité conservée : or (accent), bleu
   nuit (fond), vert = validation/temps, rouge = danger/pénalité. */
