* Encapsulating the "why we hide/show" something
Prior to this commit, we were relying on our views/templates to
understand why it might want to append the "hidden" dom class. That is
not ideal, because it required repeating knowledge about the conditions
of the policy outside of the policy's domain.
With this commit, we're removing a duplication of knowledge; or more
appropriately asking the steward responsible for the knowledge to
produce the answer.
* Refining the note to not describe a course of action
