/* Harvester — connectors workzone diagrams.
   The connector layer: the source-specific contract surface a connector owns
   (extract + normalize, plus the list_catalog and check_connection operational
   capabilities) handing off to the shared pipeline, the manifest → UI mapping
   that drives the add-source form, the built-in catalog table, and the
   custom-connector recipe. Reuses module.css primitives (mod-card,
   decision-box); adds the page-only contract cards, the declaration→UI map,
   the catalog table, and the dark IDE block (pseudocode + package tree).
   Loaded by _workzone/connectors.html on top of ../../module.css.
   Placement convention: docs/architecture/README.md §Styling. */
