/* setconnect operator dashboard.
 *
 * Built as studio hardware rather than as a web dashboard: a rack of machines,
 * each a row of channel strips. Two rules hold the whole thing together —
 *
 *   1. Colour only ever means signal state. Green, amber and red are the dBFS
 *      scale, the same one the desktop meters use. Nothing is coloured to
 *      decorate, and there is no brand accent competing with the signal.
 *   2. Monospace only ever means measurement. Timecodes, dB, byte counts and
 *      channel numbers, so digits never shift as values tick.
