{# The badge asks the service, not the row.

   It used to ask item.is_released(), which reads the item's own two columns
   and nothing else, and it lied in both directions: a page inside a withheld
   course showed as Visible while readers got a 404, and a hidden item with a
   date announced a release that was never going to arrive.

   Four states now, because "withheld" was hiding two different situations
   and a teacher needs to know which screen to go and fix. #}
