/* ==========================================================================
   Console — the panel's whole visual system.

   World: rack-mounted control hardware under work light. Painted graphite steel,
   panels seated *into* the chassis with a hairline top-light edge and a title strip
   stamped across the top. Three state roles borrowed from real control rooms:
   signal green is nominal, sodium amber is attention and every primary control,
   crimson is owner-only and destructive. Data is monospaced with tabular figures
   because operators compare columns of numbers, not because it looks technical.

   Dark only, and not by category habit: the scene is one person at a desk at night
   dealing with something happening in a server right now.
