 Because of that, the stores are not free-floating objects: they must be accessed during component initialisation, like anything else that would be accessed with `getContext`.
 
-- `getStores` is a convenience function around `getContext` that returns `{ navigating, page, session }`. This needs to be called at the top-level or synchronously during component or page initialization.

-The stores themselves attach to the correct context at the point of subscription, which means you can import and use them directly in components without boilerplate. However, it still needs to be called synchronously on component or page initialization when `$`-prefix isn't used. Use `getStores` to safely `.subscribe` asynchronously instead.

 - `navigating` is a [readable store](https://svelte.dev/tutorial/readable-stores). When navigating starts, its value is `{ from, to }`, where `from` and `to` both mirror the `page` store value. When navigating finishes, its value reverts to `null`.
 - `page` is a readable store whose value reflects the object passed to `load` functions — it contains `host`, `path`, `params` and `query`. See the [`page` section](#loading-input-page) above for more details.
