I’m learning Next.js App Router and trying to understand some architecture decisions.

A few things confuse me:

What exactly counts as server-side rendering in Next.js? If page.tsx is async and fetches data, is that already SSR?
What is route.ts really for? Is it only for API endpoints?
Why do people say we shouldn’t call our own route.ts from a server page?
Why do many projects use a services/ folder for SSR instead of fetching directly in pages?
Is a service layer mandatory, or just a clean architecture pattern?
