{# Navbar notifications dropdown — a no-JS <details> menu whose count + items

   #fcu-notifications fragment from construct.notifications_url). Included in
   base_full.html for the initial/full-page render and returned verbatim by the
   /_construct/notifications endpoint for each poll. Requires `construct` in
