 WRNexus is an SSR-first, Bun-powered full-stack framework with reactive components, layouts, colocated APIs, browser functions, lifecycle hooks, state watchers, client-side navigation, and reusable UI components.
 
+Typed declarations work across props, state, and functions:
+
+```wrn
+component UserCard {
+  types {
+    interface User { id: string; name: string }
+  }
+  props {
+    user: User
+    compact: boolean = false
+  }
+  state selected: boolean = false
+  functions {
+    function select(user: User): void {
+      selected = true
+    }
+  }
+  view { <article>{user.name}</article> }
+}
+```
+
+The extension shows declared prop types and reports missing required props and incompatible values. Typed prop and state expressions passed into nested components retain their declared type.
