Compare: overlay two curations pair by pair, aligned
Open two curations with the same number of items in Compare and step through them pair by pair. Pass an alignment JSON as align= in the URL and image B is warped onto image A. The overlay gains Difference and Tint blends: what matches fades out and only what differs stands out. Try it with two editions of the Genji Hyakunin Isshu (hikime and kaimoku).
