   RABBANI — Scholar / Admin workspace

   one sitting, so this shell is denser and more utilitarian than the student
   app — deliberately. What it must never become is the old mixed sidebar: no
   lessons, no reviews, no student destinations appear here, and the rail exists
   only on workspace routes.
