Forgot to mention originally, but I did try Zotero's snapshot feature. It seems to work better for some papers than others - the activation atlases one (https://distill.pub/2019/activation-atlas/ https://distill.pub/2019/activation-atlas/) is particularly bad. As you note, the hoverable citations and notes are also a problem. It's not that I have any pressing need for offline copies at this precise instant, but they have proven useful on a number of occasions.
