I've had this bad idea for years, but Service Workers have always been black magic to me. So I asked Claude for help and we built swiiifz¹: a static #IIIF served from a single zip file by a Service Worker, no server needed, and viewed in Triiiceratops².
Just a proof of concept, nothing to take too seriously.
