Eh, it is what it is. I could sideload if I really wanted to.

After more effort than it should have taken (for some reason my PIA app or Android was bouncing local connections even with the settings to allow it enabled) ebooks do work. Probably not well enough for me to actually use it, though. It only turns pages with swipes and doesn't really give any ways to do formatting. I'm surprised I've seen it suggested by people for ebooks with how limited it is. (I fully understand that it's not the priority development-wise).

But at least I finally set up docker, which I've meant to do forever.
