/**
 * Mobile Filters CSS — Bottom Sheet (<768) / Drawer droit (768–1023) pour catalogue PAC Air/Eau
 * Kadence Child Theme — Mon Énergie
 *
 * Stratégie (variante équilibrée) :
 *  - UNE seule bottom bar (fusion de l'ancienne barre haute + ancienne bottom bar fixe).
 *  - Panneau monté paresseusement via <template> au 1er clic (zéro nœud au chargement).
 *  - <768px : bottom sheet (translateY). 768–1023px : drawer droit (translateX). >=1024 : masqué.
 *  - Animations transform/opacity ONLY. Contrastes AAA visé. Cibles tactiles 44px.
 *
 * @package KadenceChildME
 * @since 1.2.0
