   3D PIOLA STORE — design tokens
   Paleta: azul eléctrico sobre navy casi negro, con un acento ámbar
   (el brillo del filamento/hotend) reservado para precios y detalles.
   Tipografía: Sora (display, geométrica, con carácter "tech/print")
               + Inter (texto, muy legible en español).
   Firma visual: líneas horizontales finas que evocan las capas de una
   impresión 3D — aparecen en el panel del hero y como separador de
   secciones, no se repiten en todos lados.)
