+<!--
+  /admin/* layout — auth guard only.
+
+  The nav-tabs and dashboard chrome moved into individual workbench
+  cards (admin, admin-users, admin-system, admin-user-data,
+  complexity). Each card owns its own header and renders equally well
+  inside the workbench or under its own /admin/* route wrapper.
+
+  This layout's only remaining job is to keep non-admin users out of
+  the /admin/* URL space. The cards themselves also re-check the role
+  inline because they can be rendered in workbench scenes outside this
+  layout's scope.
