/* =============================================================================
 *  ✨ xsDialog — modale de confirmation / alerte / saisie premium
 *  Remplace les window.confirm() / alert() / prompt() natifs du navigateur
 *  (laids, hors charte, en langue système) par une fenêtre raccord avec le design.
 *
 *  - Theme-aware : utilise les tokens du site (--surface, --border, --text…)
 *    avec des fallbacks → fonctionne en clair ET en sombre.
 *  - 3 tons : brand (orange, défaut), warn (ambre), danger (rouge).
 *  - Accessible : role=dialog, focus-trap, ESC/Entrée, backdrop, reduced-motion.
 *  Classes préfixées .xsd-  (xs-dialog) pour éviter toute collision.
