Start with the durable path
Most public pages need to be quick to read, easy to change, and straightforward to hand off. Pre-rendered output often makes that path easier to inspect: the page is already there, with less work required at request time.
Keep the dynamic part narrow
Authentication, transactional workflows, and private applications have different requirements. They can sit behind a focused boundary while the public site, documentation, and help content remain fast and predictable.
What still needs care
Static output still depends on domains, builds, accounts, dependencies, client-side code, and hosting configuration. The point is not that risk disappears. The point is that the public system becomes easier to reason about and recover.
For launch review, use the static launch checklist.
