I found a tutorial from 2010, which walked me through stitching flat images. I followed it, and got better results, but with the top and bottom clipped off.
What appears to be happening is that it is calculating the final size as though the images were being horizontally stacked. I rotated the images and followed the tutorial again. This gives me a different focal length for the lens, and hence a different FOV. I no longer get the clipping, but I do get the distortion again.
