// Publish the built playlist + guide to chillidonut.com/junk/iptv/ on GCS.
//
// SAFETY: uploads to two EXPLICIT object paths with `gsutil cp`. `cp` is additive —
// it only creates/overwrites the exact objects named. It never lists, syncs, or
// deletes, so NOTHING else under junk/ can be affected. (`gsutil rsync` and
// `gsutil rm` — the only commands that delete — are deliberately not used.)
//
// `-Z` gzips on upload and sets Content-Encoding: gzip (served compressed; the
// ~32 MB guide travels at ~3-4 MB). url-tvg stays …/guide.xml — do NOT pre-gzip.
//
// AUTH: needs a current gsutil token. If you see "Reauthentication required", run
// `gcloud auth login` once. (That CLI token is separate from the ADC that
// `hugo deploy` uses, which is why hugo can deploy while gsutil is stale.)
