Ok who wants to help me understand nextjs app router? And ‘use client’ vs ‘server-only’? 

I’m not used to not being able to have any “useState()” functions wherever I want??

we learned a lot while migrating @hypersub to the app router (from Next 12, where we initially began dev on it).

ideally, the `use client` boundary should be as far “down” the tree as you can get it.

if you can identify/distill client components down to their interactive elements, and use server components for server things “higher up”, I think that’s a sign you’re moving in the right direction.

router.refresh will trigger re-fetch/re-render on server components as well.

requires a change to the mental model, certainly.
