Approved. Non-blocking: while rereading the doc, I noticed we use build-time validation a few times. I wonder if people will know what that is if you don't explain it upfront. Maybe we replace with with prerendering, since build-time validation is more of an internal framework process. It's good to be aware of it, but what a user should know is that there is a prerendering process, and if that doesn't happen, then the route will render at request time, and you need Suspense (should we also mention loading.ts?)
