cdn.uhhm.no is real: releases publish to the git-pages CDN

The advertised import URL now exists. The CDN is just a pages site
(PAGES.md pattern): DNS + allowlist TXT in terraform, _headers for CORS
and immutable caching, and the release workflow PATCHes each version's
bundle in — incremental, so old versions persist. Verified in real
Chromium importing buuh@8.0.0 from the live CDN via an import map.
