/* ============================================================================
 * GamePanel — Dashboard V2 (refonte moderne, ambiance gaming saisonnière)
 *
 * Tous les selectors sont scopés sous `body.ui-v2` pour ne JAMAIS impacter
 * la V1. Charger ce fichier inconditionnellement est sans effet quand
 * `body.ui-v2` est absent.
 *
 * Stratégie : on garde le DOM existant, on ne fait que restyler.
 * Les couleurs viennent toutes des tokens CSS du thème actif (--accent,
 * --game-color, --bg-*, etc.) → l'ambiance saisonnière sort gratuitement
 * via le sélecteur du thème (winter/spring/summer/autumn/classic/v1).
 *
 * Composants traités :
 *   - Hero banner (injecté par app.js juste avant #dashboard-cards)
 *   - Page header (typo XL + gradient text)
 *   - Servers grid (espacement aéré, animation d'apparition)
 *   - Server cards (halo neon, lift au hover, bordure animée gradient)
 *   - Stats grid (numbers XL, glow border, micro-anim)
 *   - Player bar (épaisse + inner glow)
 *   - Status badge (pill avec halo)
 *   - Sidebar (logo plus présent, nav-items fluo au hover)
 *   - Topbar (verre dépoli)
 *   - Boutons d'action (pill + halo couleur jeu)
 *   - Particules de fond (subtiles, CSS only)
 * ========================================================================= */
