+Introduce a new way to encapsulate extension kinds that replaces the extension creator pattern with `createExtensionBlueprint`
+
+This allows the creation of extension instances with the following pattern:
+
+```tsx
+// create the extension blueprint which is used to create instances
+const EntityCardBlueprint = createExtensionBlueprint({
+ kind: 'entity-card',
+ attachTo: { id: 'test', input: 'default' },
+ output: {
+ element: coreExtensionData.reactElement,
+ },
+ factory(params: { text: string }) {
+ return {
+ element:
{params.text}
,
+ };
+ },
+});
+
+// create an instance of the extension blueprint with params
+const testExtension = EntityCardBlueprint.make({
+ name: 'foo',
+ params: {
+ text: 'Hello World',
+ },
+});
+```
