/* TerminalUI docs site chrome — injected on deploy and into the local
   preview template. Theme model matches docc-render's own: the body carries
   data-color-scheme (light | dark | auto, persisted in
   localStorage "developer.setting.preferredColorScheme"); auto and
   attribute-less pages follow the OS scheme. All components consume the
   token layer below, so the three-way toggle works everywhere. */
