Forcing catch-all page to override specific route

[aquelemiguel]

I have a dynamic route src/app/[brand]/[[...route]] and a specific route src/app/[brand]/login/page.tsx. I'm creating a route guarding middleware that aims to toggle (based on a feature flag) between serving the catch-all page or the specific login page for this specific path.

How would I accomplish this?
The specific route seems to always override the catch-all page.

Running Next 14 and the app router.
