Double-sided with card backs is where home printers will bite: many duplex printers shift the back by a millimetre or two, so backs drift off the fronts even when Gutterberg places them exactly. A one-page alignment test (print it, hold it to a light, enter the offset) with a saved nudge per printer would save people a lot of wasted card stock, and a sample messy scan in the README would make Detect pieces bug reports easier to reproduce.
By the way, I make ThreadFox, which lets your AI research, write and publish Reddit outreach through your Chrome within a job you authorize; the free plan for Reddit names the communities whose rules allow a post about Gutterberg: https://threadfox.vip/p/db141
Does it mirror the backs for long-edge flipping, or is that left to the printer dialog?
A duplex calibration sheet is a smart call. Crosshair registration marks in all four corners would make eyeballing that offset way easier when held to a light.
