 * valid Standard.site posts, so they surface in Sifa's activity stream and

 * leaving genuinely authored Standard.site posts (Leaflet, pckt, Offprint
 * essays) untouched.
 *
 * Signals, most to least reliable:
 *   1. The Skyreader provenance marker on the document (`skyreaderLinkblog`).
 *   2. The document's parent publication is itself a linkblog (the marker
 *      lives on the publication even when older documents lack their own).
 *      Callers resolve the publication and pass `publicationIsLinkblog`.
 *   3. A `links` entry with `rel: "repost"` — a quote-reshare, inherently
 *      not the user's own writing.
 *   4. Heuristic: a `links` entry with `rel: "related"` pointing to an
 *      external host different from the document's own publication host —
 *      the document's subject is an off-site article. Only applied when the
 *      caller supplies the resolved `publicationHost`, so an authored post
