React extensions

shadlet ships its component library, but advanced developers are not trapped inside it. Extensions are explicit React adapters registered at runtime.

import { loadExtension } from "@/extensions";
import { MyWidgetAdapter } from "./my-widget";

loadExtension({
  name: "acme-widgets",
  version: "1.0.0",
  components: { MyWidget: MyWidgetAdapter },
  styles: ".my-widget { ... }",
});

The adapter receives AdapterProps (props, children, slots, events, dispatch, navigate, route, nodeId) and renders genuine React. Callbacks are never serialised; use dispatch(eventName, payload) to invoke the Python handler bound to that event id.

Custom React functions cannot be serialised into Python. Use explicit component types and props only.
