   Housing is dark; the chart paper is the only lit surface. Every interactive
   component here carries the seven states Operate mode requires — default,
   hover, focus, active, disabled, loading, error — and no state is signalled by
   hue alone, so a console stays readable when it is dimmed, printed, or read by
   someone who cannot separate red from green.
