A note to anyone who may be having this pdf professionally printed and bound, like I did:
The pagination is messed up. Specifically, odd-numbered pages are on the left and even-numbered pages are on the right, which is the reverse of what should be. This means that two-page art spreads instead wrap around a page turn, as does the timeline. It doesn't mean the book can't be read, but it is annoying.
So if you're gonna get it printed double-sided, have them either add a blank page after the title page, or have them remove the credits page, and then everything will line up like it should.
