/* JERAP BIM Studio · «Modela con Rumi. Mide, programa y presupuesta con Quipu.»
   Plan: dos plugins con el mismo peso. Rumi = el plano (azul, cotas, edificio 3D); Quipu = el tejido andino (cuerdas,
   nudos, paño cálido) y la pantalla oscura de la propia app. Una cuerda une las dos escenas de la portada.
   Archivo (ancha) para títulos, Manrope para el texto, monoespaciada para cotas y códigos. */
