<h1>Widget gallery — the instrument-console kit, fully driveable</h1>
<div class="mastrow">
<div>
<p>Every control + display idiom in the dupre faceplate language, merged into one live console — the base kit,
the candidate batch, and the growing reference batch (R: modeled on period hardware), all rendering from
the same tokens the net / bt / sound panels use.
<b>Controls</b> take input; <b>meters & gauges</b> show a live analog value; <b>indicators &
readouts</b> show state or a number. Every widget is operable: drag the faders, knobs and gauges; click the
switches, keys and lamps. Each card carries a live readout that tracks what you do. The trace displays run
a live signal; the pointer types drive from your drag.</p>
