/* ============================================================
   Shell of the v2 thin client, rendered by the server (light DOM): app bar (App button,
   shortcuts of the pinned apps, user box and account popover), page head, page aside
   (aside-host.js), login card. Ported from the v1 SPA (engine/ui/src/engine.css): same
   classes, so the server renders the v1 markup. No inline styles anywhere (CSP): the
   layout of the rx-app-shell slots uses .x-appbar / .x-appbar-actions.
   Tokens come from ./wc/theme.css.
