/* Proofred web app — the flat surface of the design system.
 *
 * Per the handoff: settings and the dashboard are full Modernist — flat,
 * square, ruled, no glass, no elevation. Radius is 0 everywhere on purpose;
 * the 2px rules and the alignment do the organising. Glass and rounded
 * corners belong only to extension chrome floating over a host page, which is
 * not this.
 *
 * Light only. The design system is a light-ground system and every mockup is
 * built on it; bolting a dark theme onto it would be inventing a half of the
 * system that does not exist.
