/*
 * Minimal classic theme.

 * Everything is driven by the custom properties in :root. Light is the base; the dark
 * block redefines only the tokens, never the rules, so there is one set of styles to
 * maintain rather than two.
 *
 * Fonts are system stacks on purpose. A webfont would mean a network request the
 * offline-first PWA cannot rely on, and a flash of unstyled text on every cold start.
