When migrating from the Pages Router to the App Router in Next.js 15, which of the following is the primary advantage of the App Router's file-system-based routing regarding server-side rendering (SSR) and data fetching?
In the context of Next.js 15's App Router, what is the primary role of a `layout.js` file within a directory, and how does it differ from a `page.js` file?
Consider the following Next.js 15 App Router file structure. If a user navigates to `/dashboard/settings/profile`, which `page.js` file will be rendered, and what layout structure will be applied? ``` app/ ├── layout.js ├── page.js └── dashboard/ ├── layout.js ├── page.js └── settings/ ├── layout.js └── page.js ```
