   MATERIALES — COTIZADOR DE PLAQUETA + INFOGRAFÍAS
   --------------------------------------------------------------------------
   CSS propio de la sección de plaqueta dentro de /materiales.

   No se recompila Tailwind para esto: el CSS compilado
   (assets/css/tailwind.css) lo comparten ~200 archivos y recompilarlo
   arriesga las clases que ya usan las paginas existentes. Por eso todo lo
   especifico vive aqui, con los prefijos "pq-" (cotizador) y "ig-"
   (infografias de producto).

   El cotizador conserva el prefijo "pq-" porque su JS
   (assets/js/plaqueta-cotizador.js) lo consulta por id.
