`/collections/amadoras-mythology` and `/collections/70s` are the same page with a different subject.
Building each would be absurd; hard-coding the arrangement would put it out of reach of the admin. So
the arrangement is built once — a template page, composed exactly like any other — and every
collection is drawn through it.
Four blocks read the subject: its name, its description, its specs, its photographs. They hold nothing
at all, not even a reference. `collections` holds no content because the list is a query; these hold
none because the subject is the URL, and the same block draws a different collection on the next
request.
Offered only on a template, and HIDDEN rather than disabled elsewhere. A greyed-out row invites "why
not here", and the answer — this page has no subject — is not something a tooltip fixes. Available and
silently drawing nothing is the worse failure.
