/*
 * Advanced Forms Builder — styles front-end
 *
 * Principe d'intégration au thème actif :
 *  - les règles STRUCTURELLES (largeur, grille, boîte) sont écrites avec une
 *    spécificité suffisante pour ne jamais être cassées par le thème ;
 *  - les règles DÉCORATIVES (couleurs, bordures, arrondis, espacements internes)
 *    sont enfermées dans :where(), donc de spécificité 0 : la moindre règle du
 *    thème (par ex. `input[type="text"]`) les remplace automatiquement ;
 *  - les couleurs proviennent des presets WordPress du thème
 *    (--wp--preset--color--*), avec un repli calculé en PHP depuis theme.json.
 *
 * Le mode « Style autonome du plugin » (.afb-style-plugin) force au contraire
 * l'apparence du plugin.
