   ------------------------------------------------------------
   Toda la paleta sale del logo, muestreada del archivo original:
     #081820  texto del lockup .... el oscuro de la marca (no negro)
     #E4B400  arco de abajo ....... oro, bajado a latón #C9A227 en el sitio
     #9C9C9C  edificio ............ gris

   Un solo acento, en dos intensidades:
     · sobre oscuro  → --gold   (botones, números, antetítulos)
     · sobre claro   → --ember  (el mismo oro oscurecido, para que contraste)
   El rojo del arco superior vive solo dentro del logo.
