rays 373f862588 A page older than its script is loaded again, not run with it (#449) ...

Safari on a Mac threw at load on 2026-11-10: the script wired #sleep,
which the page it ran in did not have. #sleep and its script came in
together on 11-08, so the page was older than the script. The service
worker answers a navigation it cannot fetch with the page it kept last,
here one from before 11-08, and that page asked for its script by the old
hash; by then the network answered, and Caddy, which ignores ?v=, sent
today's app.js. The worker even kept it under the old name.

Every ?v= is the first 12 hex digits of the file's SHA-256, so the worker
now checks what it fetched against the name. On a mismatch it does not
keep or give the file, and loads the page again from the network, at most
once in 30 seconds so a page still unreachable is not reloaded round and
round.
