/* Design system for the household finance dashboard.
 *
 * This is an instrument panel, not a document: it gets scanned and operated,
 * so state is encoded in form as well as number, and the categorical ramp is
 * kept separate from both the accent and the semantic good/bad colours.
 *
 * Themes: the media query carries the OS preference; [data-theme] on <html>
 * carries an explicit toggle and must win in both directions. Components only
 * ever read tokens, never raw colour.
