The booklet will be send to print services in A4 in regular page order,
as a PDF. They'll resize and reorder to make a booklet.

However, the centrefold should not be resized. It's A4 and should remain
A4 so it occupies two A5 sheets.

This suggests we should send it to print services as a separate file.
But maybe their software can handle it all as one PDF.
