/* Lassy Meet — app frame, toasts, menus and dialogs.

   There is no chrome: no app rail, no title bar, no search. A guest opening
   a join link gets the meeting filling the window, which is what the real
   join-by-link client does. What remains here is the frame screens mount
   into, and the layers that float above it.
