So my guess it's formatting inserted during the conversion by calibre, and can safely be removed.

Okay, now that I've had a chance to look through some of my Kindle -> EPUB conversions...

The second book I opened, copyright 2014 and converted in January 2015, repeatedly uses <div class="mbp_pagebreak"/> in the middle of its two text documents to separate chapters. (The first document is frontmatter and a serial story, and the second is an unrelated story with backmatter.) There is an additional instance at the top of the second document.

I am strongly tempted to label this a Calibre issue, an artifact of the conversion process that should be handled by adjusting that feature. That doesn't do anything about any existing conversions, though, so I haven't completely (ahem) closed the book on it yet.

If I do include processing for this, it'll definitely be tied to "is a BODY tag adjacent?" and will handle cases - such as this one - where there's no "calibre_pb_\d+" ID attribute present. That does make things more complicated, though, and further feedback is welcome.

Meanwhile, I've received a copy of the page-count plugin and information on the checkbox tweaks, so I can look into that. If they're as minor as they sound, I have no qualms about porting them over. Optional feature, doesn't break anything - sounds like a win.
