That accordion was included for publication pages' sake, but those don't appear to have files attached to them anymore (at least not the ones on prod).

In order to guard against regressions (i.e. in case a publication pops up with attached files again), could we make the inclusion of that detail section dependent on an optional prop and pass it in on the publication page side? e.g. includeAccordion

Ah good idea! I'll add that in.
