<p>Two backend pieces support browsing the full server catalog while offline
and queueing downloads that fire on reconnect:</p>
<ul>
<li><a href="fn.sync_full_catalog.html" title="fn jellytau_lib::commands::catalog::sync_full_catalog"><code>sync_full_catalog</code></a> walks every library while online and persists all
items to the offline cache so the whole catalog is browsable (greyed out)
offline. It reuses [<code>HybridRepository::cache_items_from_server</code>], which in
turn reuses <code>OfflineRepository::save_to_cache</code> (sets <code>synced_at</code>, which is
what <code>get_items</code> branch 3 serves offline).</li>
<li><a href="fn.resume_queued_downloads.html" title="fn jellytau_lib::commands::catalog::resume_queued_downloads"><code>resume_queued_downloads</code></a> resolves and pumps the <code>pending</code> download rows
that were queued offline (they have <code>stream_url IS NULL</code>), mirroring the
heal-and-pump pattern in <code>player_preload_upcoming</code>.</li>
</ul>

never answer an artist query and those groups can only ever be filled by the
