/* Shared base for every dropdown menu in the app (prompt picker, chat

   The outer box owns the border/radius/shadow and clips its content
   (overflow: hidden) so nothing — including the inner scrollbar's thumb —
   can poke past the rounded corners. The inner .dropdown-menu-scroll is
   the actual scroll container, kept free of its own border-radius so the
