/**
 * JS twin of the `fragment_url` SQL predicate below.
 *
 * Google does not index fragments as distinct entities — a `#anchor` URL always
 * resolves to its parent document — so inspecting one can never return a useful
 * verdict, and counting one inflates every per-URL total by a phantom row. Write
 * paths reject these; read paths exclude them.
 *
 * Kept beside {@link INDEXING_ISSUE_FILTERS} so the JS and SQL sides of the rule
 * cannot drift; call sites must use this rather than re-deriving `includes('#')`.
