/* BadgeLock console — visual system
   Subject: badge readers on walls, locked workstations, audit trails. The console borrows the reader's own
   status language (an LED per computer, a dark faceplate for state) and otherwise stays quiet: cool paper,
   white cards, one cobalt for actions, monospace for anything a reader or a log produced. */
