 * `panelRegistry.panelForKind`) — but which *section* of the Nature panel to
 * show is plugin knowledge, so the plugin listens too and points its own store
 * at the found node's section + preset. Module-level (imported by the plugin
 * manifest) so the listener is live from plugin load, even while the panel has
 * never been mounted.
