/**
 * ui-feedback.css — Styles des primitives UI partagées Sportify
 * (FEATURE-045 / TASK-173)
 *
 * Toasts (notifications non bloquantes) et dialogues modaux asynchrones.
 * Variantes : success, information (info), warning, error, destructive.
 * Charte Sportify : gradient #FFE5CC -> #FFD4A3 -> #FFC078 -> #FFB366.
 * Mobile-first, responsive, prefers-reduced-motion respecté.
 *
 * Les tokens de couleur de statut et le z-index d'overlay sont définis dans
 * common-styles.css (:root) pour éviter toute duplication de la charte.
