   VELUM — Sistema visual
   Estudio-laboratorio de envolventes arquitectónicas.
   Tipografía: Monda (display) + Manrope (cuerpo).
   Acento institucional: Bronce #B5794A (tomado del isotipo).
   ------------------------------------------------------------
   Principios:
   1. El acento es escaso. Solo acción y destacado.
   2. La jerarquía se resuelve con escala y aire, no con cajas.
   3. La trama es detalle de esquina, nunca fondo de texto.
