/*
 * Clareza Acadêmica — vitrine de simulados.
 * Escopo exclusivo de /simulados/.
 *
 * Reúne dois blocos <style> que viviam nos templates:
 *   - o da própria página (era um <style> no bloco extra_css);
 *   - o do cartão (templates/simulados/partials/simulado_card.html), que ficava
 *     DENTRO do include e por isso era repetido uma vez por cartão renderizado.
 *     O comentário lá dizia "só renderiza 1x graças ao cache do browser", o que
 *     não vale para <style> inline: cada cartão trazia a folha inteira junto.
 *
 * Continua sendo uma vitrine com três modos de exibição (agrupada por
 * categoria, agrupada por subcategoria e lista paginada). A arquitetura de
 * listagem foi preservada; o que mudou é a linguagem visual.
