+ * `calendar` / …) key of its own — a per-visualization field binding cannot
+ * be declared directly on `interfaceConfig`. The one schema-legal channel is
+ * `sourceView`, which objectui's `InterfaceListPage` resolves against the
+ * source object's OWN named view and (since objectui#5908) forwards that
+ * view's `map` block verbatim to the renderer. `showcase_task` already
+ * declares the correct binding on its `map` listView (task.view.ts, #9340);
+ * this page has to REFERENCE it, or the renderer's `titleField || 'name'`
+ * fallback finds no `name` field on `showcase_task` and every marker title
+ * renders as a placeholder.
