Policy note: ignore running footer content
Throughout the book, Bowen has running footers in the chapters, e.g. "Bowen, Chapter 1, Page 1."
I think we're safe to ignore these, since they're not actually important content to import into Editoria, and we're removing the pagination by going to HTML.
Nothing to do about this one, just noting this - @wendell you can close this one out when you see it!
