/**
 * SAGY Auto AI — FAQ Accordion Front-End Styles v2.2
 * Suporte a variáveis CSS configuráveis pelo painel interno.
 *
 * INTEGRAÇÃO INBRMFA:
 * Quando o INBRMFA está ativo, o PHP não injeta as vars --sagy-faq-* em :root
 * (vide FaqAccordion::enqueue_frontend). As vars abaixo servem como fallback
 * quando o INBRMFA NÃO está ativo.
 *
 * Classe dupla de estado:
 *   .sagy-faq-open         → classe do SAGY (usada pelo JS do SAGY)
 *   .rm-faq-question-active → classe do INBRMFA (usada pelo JS do INBRMFA)
 * Ambas recebem os mesmos estilos visuais de "aberto" para que
 * o accordion funcione visualmente com qualquer um dos dois JScripts.
 *
 * ESTRUTURAS SUPORTADAS:
 *   A) Rank Math ativo (frontend renderizado):
 *      #rank-math-faq > .rank-math-list-item > h3.rank-math-question + div.rank-math-answer
 *   B) Gutenberg raw (Rank Math inativo):
 *      .wp-block-rank-math-faq-block > .rank-math-faq-item > h3.rank-math-question + div.rank-math-answer
 *   C) HTML puro gerado pelo SAGY:
 *      .sagy-faq-section > .sagy-faq-item > h3.sagy-faq-question + div.sagy-faq-answer
