   ESCALA FLUIDA
   El diseño original está trazado sobre un lienzo de 1600 px. Todas las
   medidas se expresan en `rem` sobre ese lienzo y la raíz escala con el
   ancho de ventana (1rem = 1vw, tope 16px). Resultado: la página reproduce
   las proporciones exactas del diseño en cualquier ancho de 1024 a 1600 px
   —a 1280 px equivale al mockup al 80 %, a 1600 px al 100 %—.
   Por debajo de 1024 px la raíz vuelve a 16 px y toma el control la escala
   móvil definida en el bloque 13.
