   Outsource China — storefront shell

   The masthead, the corridor strip, the command palette and the footer: the
   chrome around every storefront page. All of it sits on command plates
   (--plate-*), which stay dark in both themes. Loaded by layouts/app.php only;
   the .brand lockup and the theme switch live in app.css because the admin
   and auth layouts use them too.
