   M6AYW Radio Console — design system
   --------------------------------------------------------------------------
   Dark by default: this is an instrument panel. The light variant is a
   daylight bench mode — same grid and same geometry, ink on paper, with the
   glow tokens turned off rather than restyled. The console panel itself
   stays dark in both modes, because a waterfall display always is.
