/**
* This is your entry point to setup the root configuration for tRPC on the server.
* - `initTRPC` should only be used once per app.
* - We export only the functionality that we use so we can enforce which base procedures should be used
*
* Learn how to create protected base procedures and other things below:
* @see https://trpc.io/docs/v10/router
* @see https://trpc.io/docs/v10/procedures
