Now we define the `RouteLayer`. When called, the route layer will consume text (a query) and output the category (`Route`) it belongs to — to initialize a `RouteLayer` we need our `encoder` model and a list of `routes`.

- If expecting routes to sync between local and remote on initialization, use `SemanticRouter(..., auto_sync="local")`. Read more about `auto_sync` and :doc:`synchronization strategies <route-layer/sync>`.
