The hull test, at every flood step from 4 to 14, and not the lean: a drawn card clears every check out to 60 degrees, so what the refused frames have is a soft outline rather than an angle. The open question moves to what `LEAST_FILL` at 0.86 would admit, which wants the pictures holding no card. A card past 44.3 degrees is read a quarter turn, and the detection having succeeded is what stops the guessed framings being tried. What that costs has not been measured, so it is written as what it is rather than as a verdict. Signed-off-by: eth0net <eth0net@pm.me>
