/*
 * Dashboard styles.
 *
 * Colour roles come from the validated dark palette, checked against this
 * page's actual surface (#1b1f26) rather than a generic one:
 *   categorical 3 slots -> CVD worst-pair dE 9.4, normal-vision 20.9, all >= 3:1
 * Sequential magnitude uses one blue ramp, running dark (near the surface) to
 * light, because on a dark surface "more" has to mean brighter.
