/* Yellow chip rendered next to admin-only affordances on /catalog and

   couldn't tell whether non-admins also saw the button. The pill +
   title tooltip make the visibility hint unmistakable: yellow signals
   "only you see this". Non-admin viewers don't see the parent affordance
   at all (server-side {% if user.is_admin %} gate). */
