Current vs. Expected behavior

This commit outlines the issue: f5cbf18

The not-found page is dynamic, while / is expected to render statically. However, somehow the global not found page is rendered as part of /.

Output:

Error: Route / with `dynamic = "error"` couldn't be rendered statically because it used `headers`. See more info here: https://nextjs.org/docs/app/building-your-application/rendering/static-and-dynamic#dynamic-rendering

I'd expect the 404 page to be dynamic while the home page is static.
