/* ---------------------------------------------------------------------------
   Slide-in side menu (B1.church style).

   Replaces the old .admin-menu gear dropdown in the topbar. The drawer is a
   left-anchored panel that slides in over a dimmed backdrop. It must sit above
   the fixed bottom tab bar (z-index 100) and the install banner (90), hence
   z-index 150/151.

   Everything is expressed with the app's CSS variables so /theme.css restyling
   keeps working.
