/**
* The soft-refresh poller (atomic-deploys 10): a browser-side loop fetching
* the host's `/.well-known/version` and reporting when the served deploy
* fingerprint differs from the one this document was rendered from. No live
* container swap — the banner decides whether to reload (old bytes are
* retained, so a reload is always safe). Polling pauses while the document
* is hidden and reports at most once.
