/* ============================================================
   LINK BUILDING PAGE — estilos específicos de pages/link-building.html
   A propósito, esta página usa un patrón distinto al resto
   (hero de red de enlaces en vez de imagehero+curva, grilla estática
   en vez de carrusel, y el componente de gráfico animado de
   services.css que no se había usado en ninguna otra página).
   Reutiliza tokens de style.css / animations.css / services.css.
