/* AI Server control console.
   The visual language is a control-panel schedule, not a dashboard: state first,
   dense rows, unambiguous safe/isolated colouring, no decoration that is not
   carrying information.
   Type is local on purpose. Bahnschrift is Windows' DIN-derived industrial face,
   which is what panel legends are actually set in -- and an admin console must
   still render when the network it administers is down, so nothing is fetched. */
