/* i-Log 4.0 dashboard.
 *
 * Built for two panels: the 800x480 Pi touchscreen and the 1280x720 16:9 panel.
 * The look is a calm instrument face: cool mineral ground, marine-ink text, and
 * colour reserved for what an operator must act on (below / near / over the
 * baku mutu). The one distinctive element is the threshold-band gauge on each
 * reading card. The product's purple stays as the only interaction accent.
