   La luz es el material. La página es casi negra y el gabinete del
   centro arranca encendido a media luz: marco y ventiladores con brillo
   tenue, contornos al 40 % y la próxima pieza respirando en celeste con
   su rótulo ("Empezá por el procesador"). Cada pieza que elegís pasa a ser
   hardware: cuerpo oscuro, bordes celestes encendidos y detalles de
   luz propios (barra de la RAM, placa trasera de la GPU, mangueras y
   bomba del enfriador). Con las ocho piezas, el borde del gabinete se
   tiñe de violeta: es el único lugar donde aparece la segunda luz.

   Estructura (una sola rejilla):
   - ≥1200 px: portada + pasos | gabinete fijo (≈40 %) | panel fijo;
   - 720–1199 px: portada + pasos | gabinete fijo, panel en barra inferior;
   - <720 px: portada, gabinete, uso, pasos y barra inferior.

   Formas: botones y chips en píldora; panel y tarjetas en 12–14 px;
   miniaturas en 10 px. Sin bordes en las filas de los pasos: líneas
   finas y el número grande en mono como ancla.

   armador.html carga esta hoja con ?v=N: subí la versión en cada cambio.
   Va después de nc-departments.css, así que gana por orden.
