     Aha, some backward compatibility support in the ZIP processing code
for pre-ES6 clients was falling over itself on Safari. (The image,
changes, and sources are initially transmitted in ZIP files.) That code
is in a third-party library, and is complex and large; I haven't gone
through it all yet. Fortunately, the problem only happened when the ZIPs
had already been unpacked, so now I just don't call it in that case.

     Anyway, I can now load and reload successfully on latest
Safari/MacOS, and I updated https://caffeine.js.org/.


     thanks!
