   Tarjeta de artículo (.post-card) + rejilla de relacionados
   Extraído de assets/css/pages/single.css para poder usar el mismo preview
   normalizado fuera del blog: los hubs de patología y tema pintan el bloque
   template-parts/blocks/blog-relacionados.php y no cargan single.css.

   OJO: single.css y page-noticias.css conservan su propia copia de estas
   reglas. Esta hoja NO se encola en esas páginas, así que no hay conflicto;
   queda pendiente unificar las tres en una sola.
