/* =================================================================
   «PREGUNTAS FRECUENTES» (solo portada: lista de page.php en head.php)
   Réplica de material/mockup-faq.html. Reutiliza el metalizado, la
   etiqueta, el titular, el subrayado, la entradilla y el halo de Precios
   (98-precios-portada.css: .pc-*) y el cristal y la trama del planificador
   (96-plan-portada.css: .pn-card, .pn-dot); aquí va lo propio.
   Sin JS, todas las respuestas abiertas. faq-portada.js pone .fq--js
   (acordeón: una abierta a la vez) y .fq--armado / .is-in (entrada).
