/* ============================================================================
   FREZZ — style KAWAII CARTOON B (charte galaxie SANTVIA, porteur 2026-09-11 :
   base canonique de toute la flotte, vague 3 : 19/66, après `flowly`).
   Remplace le glassmorphism premium (backdrop-filter partout, ombres bokeh
   multi-layer) par le patron sticker : aplats + matière 2 tons, UNE SEULE
   ombre plate nette (zéro flou), contour épais, reflet kawaii (2e couche de
   background, jamais en ::after).
   Consolidation : ce fichier ne portait que des restes premium (particules
   canvas jamais rendues en DOM, .theme-grid/.tool-btn/#wallet-display dépendant
   de tokens --cb-* désormais retirés) — fusionné ici avec le <style> inline
   d'index.html (même sélecteurs, cascade gagnée par l'inline car chargé
   après) en UNE SEULE source ; le <style> inline a été retiré d'index.html.
   Identité conservée : tapis vert (plateau/CTA « Play »), chrome or adaptatif
   (--fz-gold, contour/HUD), fond nuit bleu marine, cartes blanches classiques
   (rouge/noir par couleur, jamais par symbole seul — accessibilité).
   Thème piloté par le hub via html[data-theme] (posé tôt par /_kit/theme.js,
   cf index.html) — plus d'OS-only @media (prefers-color-scheme).
   Contour : --toon-outline ADAPTATIF (or clair sur panneau sombre, encre foncée
   sur panneau clair) ; --toon-outline-ink TOUJOURS foncé pour les éléments posés
   sur un fond vif (tapis, boutons pleins) où un contour sombre reste lisible
   dans les deux thèmes.
