+"""Regression for #1809: document library counters must update after delete.
+
+documentLibrary.js is a browser module with several DOM-only imports, so this
+guards the relevant wiring at the source level. A single-card delete used to
+remove the card and decrement `_libraryTotal`, but the header/chips render from
+`_libraryLanguages`, which stayed stale until a full library refetch.
