   BANCO DE DEMOSTRACIÓN (demo-stage)
   Concepto: un "banco de pruebas" de taller. Banda oscura con malla de
   precisión y marcas de corte en las esquinas; el dispositivo flota sobre un
   resplandor cálido y a su lado va una guía numerada de qué tocar.
   Se reutiliza en meseros, cocina, domicilios y panel.
