Note that YAML settings cannot call any PHP functions, so you can't access helpers like env() for environment variables, nor declare authors or navigation links, as you cannot use facades and objects. https://hydephp.com/docs/1.x/customization
We should find a way to support authors and navigation links from here, possibly by matching input arrays to constructors. We may want to do this in v2 as the navigation system is reworked, so we don't introduce a change that will be broken soon.
