**The directives aren't for specifying "where the code runs" module by module. You shouldn't put `'use client'` in all frontend modules or `'use server'` into all backend modules--that's pointless!** All they do is let you create "doors" between the two module systems. They let you *refer to* the other world.

If you want to pass data from the backend to the frontend (as a `<script>` tag), you need to `'use client'`. If you need to pass data from the frontend to the backend (as an API call), you need to `'use server'`. Otherwise, you don't need either directive--you just use `import` as usual and stay in the current world.
