+Exposes `getFetchState()` from `astro/hono` as a public API
+
+The `getFetchState()` function retrieves or lazily creates a `FetchState` from a Hono context object. This allows third-party packages to build Hono middleware that interacts with Astro's per-request state, giving the `astro/hono` API the same extensibility as `astro/fetch`.
+
+```ts
+import { Hono } from 'hono';
+import { getFetchState, pages } from 'astro/hono';
+
+const app = new Hono();
+
+app.use(async (context, next) => {
+  const state = getFetchState(context);
+  state.locals.message = 'Hello from custom middleware';
+  await next();
+});
+
+app.use(pages());
+
+export default app;
+```
