+### Types global namespace
+
+The `MyTypes` module is a shared namespace that lets each feature own its local
+types while still contributing to a central app-level contract. It builds on the
+`RootState` and `RootAction` setup from the [Create Global Store
+Types](#create-global-store-types) section above.

+- `playground/typings/modules.d.ts` provides the empty ambient module that later

+- `playground/src/store/types.d.ts` augments it with `Store`, `RootAction`, and
+  `RootState`.
+- `playground/src/services/types.d.ts` augments the same module with `Services`.
+
+Because each module augments `MyTypes` independently, types stay close to the
+code that owns them instead of being collected in one giant file.
+
+```tsx
+import { StateType, ActionType } from 'typesafe-actions';
+
+declare module 'MyTypes' {
+  export type Store = StateType<typeof import('./store').default>;
+  export type RootAction = ActionType<typeof import('./root-action').default>;
+  export type RootState = StateType<ReturnType<typeof import('./root-reducer').default>>;

+This pattern keeps imports stable and makes cross-cutting app types reusable in
