/* BOXZ — style kawaii sticker (standard FACETA, cf BACKLOG.md §PIVOT DESIGN /
   §PROGRAMME AUTONOME, vague 3 : 6/66, suite alphabétique après `awalo`).
   Override LOCAL à boxz, chargé APRÈS /_kit/kit-design.css (même patron que
   faceta/triplo/mazz/melz/atouz/awalo) : contour épais net, aplats + une seule
   ombre plate (zéro flou), reflet kawaii en 2ᵉ couche de `background`, formes
   rondes. Remplace l'ancien flat-UI translucide (chips/boutons en
   rgba(...,.05-.2) sans contour marqué). Identité du jeu conservée : cyan pour
   le chrome/l'accent, bleu (P1) / rose (P2) pour les 2 joueurs sur le plateau
   (dessiné en <canvas>, cf src/game.js — lit ces mêmes tokens). */
