Lots of questions, hope you dont mind: 1. Do you have an example/recommendation on how to setup a schema for a codebase with hundreds of objects and thousands of permission combinations? Is it possible to break the schema up into sub schemas? 2. How does the node client know which schema to load? Looking at this [example](https://github.com/authzed/authzed-node/blob/main/examples/v1alpha1/example.js), is the recommendation to load the schema into memory at runtime on app startup?
