-
- - `createStore(options): Store<S>`
-   - `options: CreateStoreOptions<S>`
-     - `doc: LoroDoc`
-     - `schema: S`

-     - `throwOnValidationError?: boolean` (default `true`)
-     - `debug?: boolean`
-     - `checkStateConsistency?: boolean`
-   - Returns `Store<S>` with:
-     - `getState(): InferType<S>`
-     - `setState(updater): Promise<void>` — same updater shapes as Mirror; await in non-React code
-     - `subscribe(cb): () => void` (same metadata as Mirror)
-     - `getMirror(): Mirror<S>`
-     - `getLoro(): LoroDoc`
-
- - `createReducer(handlers) -> (store) => dispatch(type, payload)`
-   - Define an object of handlers that mutate an Immer draft. The returned `dispatch` wires those actions to `store.setState`.
-
- Example
-
- ```ts
- import { createStore, createReducer, schema } from "loro-mirror";
- import { LoroDoc } from "loro-crdt";
-
- const s = schema({
-   todos: schema.LoroList(schema.LoroMap({ id: schema.String(), text: schema.String(), done: schema.Boolean({ defaultValue: false }) }), (t) => t.id),
- });
-
- const store = createStore({ doc: new LoroDoc(), schema: s });

- const actions = {
-   add(state, { id, text }: { id: string; text: string }) {
