{# Navbar notifications dropdown — a no-JS <details> menu whose count + items
   refresh in JS mode via Unpoly polling (up-poll/up-interval reload this same
   #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
   context. #}
