   Gerege AI Nexus — console theme

   A gerege was the Mongol Empire's tablet of authority; the courier carrying
   one drew fresh horses at every relay station. The palette is that object:
   patinated bronze in shadow, struck gold where the light lands. Warm darks
   throughout — a blue-black ground would fight the gold rather than hold it.
