/* O Conselho: base visual das páginas públicas (11/11/2026).
   Nasceu no protótipo da Educação (educacao/prototipo/estilo.css): título pesado com a segunda linha fina,
   preto, branco e cinza, botões em pílula, fundo vivo e cartões com a luz que acompanha o cursor.
   Nas páginas da casa o dourado fica só nos detalhes (variável --acento). Pra uma página sem dourado,
   basta redefinir --acento e --acento-claro nela. Nada aqui toca em pixel, evento ou UTM. */
