/**
 * FSM FAQ — Estilos v2
 *
 * Linguagem visual: institucional, moderno, sóbrio.
 *   - Cartões individuais com sombra subtil em vez de lista plana
 *   - Numeração à esquerda como elemento gráfico
 *   - Acento azul institucional FSM (#2b496f)
 *   - Tipografia escalonada com hierarquia clara
 *   - Estado aberto: borda colorida à esquerda, fundo destacado
 *   - Pesquisa em tempo real opcional
 *
 * NOTA: usamos selectores específicos (.fsm-faq .fsm-faq__...) e !important
 * pontual nas propriedades de cor/fundo para sobrescrever o tema Seosight,
 * que injecta o seu próprio CSS de accordion (cor magenta/rosa indesejada).
