/* Kairos dashboard.
 *
 * Light is the base and dark is applied over it, under two scopes: the media
 * query follows the OS, and the `data-theme` attribute follows the toggle. The
 * `:where(:not(...))` guard keeps the toggle winning both directions - without
 * it, choosing light on an OS set to dark would have no effect.
 *
 * Both step sets come from the same validated ramps (light surface #fcfcfb,
 * dark #1a1a19). Dark is a selected set of steps, not an inverted copy.
 * Charts here are single-series, so there is no categorical palette to keep
 * apart; the one place hues sit together is the status chips, and each carries
 * a dot and a word so colour is never the only signal.
