@evan Anyway, I wasn't kidding.
I tend to print long documents 2-up, double-sided or 4-up double-sided depending on the font sizes. Black text on a white background is too much eyestrain for me on a backlit screen, and I often want to mark the things up and spread a bunch of stuff around on a table side-by-side.
Computers are pretty good for HTML or epub or whatever, because they just reflow to fit and you can just style them for dark mode. But PDFs are designed for printing, and have things like "pages" built into the model. If you don't want me to print it out, don't use a print-specific format like PDF!
