> A multi-resolution image format There are already quite a few cbz archives in the wild that contain jxl encoded images. That's a multi-resolution format at least to the extent that it supports progressive decoding at fixed levels that range from 1:8 to as high as 1:4096. I think it might also support other arbitrary ratios subject to certain encoding constraints but I'm less clear on that. Readers might need to be updated to make use of the feature in an intelligent manner though. The jxl cbzs I've encountered either didn't make use of progressive encoding or else the software I used failed to take advantage of it - I'm not sure which.
