/* Estilo común de las páginas propias (portada, producto, precios). Sale de la portada del 17/10/2026.
   Desde el 18/10/2026, con lo que Miguel señaló de serus.ai: lienzo casi blanco, sin líneas ni cruces
   entre secciones (las separa el aire y los bloques grises), serif de exhibición en los titulares
   grandes, lima solo en "Start free" y en puntos de estado, y heros blancos con campo de caracteres
   (campo.js) salvo el de la portada, que sigue oscuro. */
