 *   @media dark + :root:not([data-theme=light])  system dark, unless the user chose light
 *   :root[data-theme="dark"]                chosen dark, whatever the system says
 *
 * The choice itself (System / Hell / Dunkel) lives per device in localStorage
 * (`rh:theme`, js/theme.js) — it is a property of the screen, not of the
 * renovation, so it is never synced.
