/* ============================================================================
   4-game-shell.css
   ----------------------------------------------------------------------------
   Shell commun des mini-jeux (connect4, chess, uno, poker, monopoly, werewolf).

   ARCHITECTURE
   Trois couches superposées :
     1. TOKENS     : --gshell-*  (palette, rayons, motion, safe-area)
     2. PRIMITIVES : .gshell-*   (composants génériques sans couleur dure)
     3. THEMES     : .gshell-theme-<jeu>  (1 classe, overrides de tokens)

   IDENTITÉ PAR JEU
   Deux façons d'appliquer un thème, au choix (les deux coexistent) :
     A) classe helper : <main class="gshell-page gshell-theme-connect4">
        → applique tous les tokens du jeu en une classe.
     B) tokens inline : .connect4-page { --gshell-accent: #2563eb; }
        → pour les jeux qui ont déjà un conteneur préfixé ; permet un
        override plus fin (accent-2, board-bg, etc.) sans toucher le HTML.

   CONVENTIONS
     - État       : .is-active / .is-hidden / .is-disabled / .is-loading
                    (support legacy : .active sur les overlays)
     - Élément    : .gshell-<bloc>__<élément>
     - Variant    : .gshell-<bloc>--<modifier>

   ADOPTION PROGRESSIVE
   Ces classes coexistent avec les préfixes existants (.connect4-*, .chess-*…).
   Aucun jeu n'est forcé de migrer d'un coup. Spécificité faible → un override
   jeu reste toujours vainqueur.

   DÉPENDANCES
   1-base.css doit être chargé avant :
     --safe-area-* / --space-* / --radius-* / --bg-* / --text-* /
     --accent-*   / --ease-*  / --duration-* / --z-* / --shadow-*.
