registerComponentDecorator

registerComponentDecorator<P>(componentName, plugin): void

Decorate a named slot — add UI before/after/around it or transform its props.

Slots are mount points the SDK exposes for plugins to inject custom UI without forking the editor. Common slots include 'OptionalAppBarControls', 'OptionalNodeContent', and others — see the Build a plugin guide for the authoritative list.

Safe to call more than once; pass plugin.name to deduplicate.
