suppose this is my project structure and i want home and movies to have a shared layout (after logging in ) and signup to have a different layout. how do i go about this? i don't want change in routing structure so I cannot push home and movies to a newer folder inside app/ because that will create a different routing structure. i want routing to go like - xyz.com (signup), xyz.com/home(user homepage), xyz.com/movies(user movies page).

.
└── src/
    └── app/
        ├── home
        ├── movies
        ├── signup
        ├── layout.tsx
        └── page.tsx
