/* DATABRIDGE dashboard.

 * Written for a phone held in a plant room, in daylight, by someone wearing
 * gloves: big targets, high contrast, no hover-only affordances.
 *
 * Colours are the validated eight-slot categorical palette plus its chrome and
 * status roles. Dark mode is a selected set of steps for the dark surface, not
 * an inversion, and the theme toggle wins over the OS setting in both
 * directions.
