4// installability requirement (a registered SW with a fetch handler). It caches
5// NOTHING, so it never conflicts with the nginx chunk-cascade versioning
6// (the v-1/v-2/v-3 rotation in the Dockerfile). Do not add offline/app-shell
7// caching here without coordinating with that rotation, or stale clients will
8// be served mismatched hashed chunks.
