{# The footer's content, as its own fragment: included by base_full.html inside
   {% block footer %} and served by /_construct/footer. With footer_poll on,
   the content is wrapped in #fcu-footer-content, which Unpoly reloads from
   that route on a timer; with it off the content renders bare, as before.
   The route passes footer_fragment=True so the element is returned even when
   the content is empty. Requires `construct` in context. #}
