/**
 * Modal de Cobrança - Enterprise Edition CSS v8.4 (Animação Centralizada)
 * @version 8.4.0 - REMOVIDO: A animação de transform/opacity foi removida deste arquivo.
 *                  A responsabilidade da animação agora é 100% do sistema global em _modal-animations.css,
 *                  resolvendo o conflito do "efeito mola".
