What is the Next.js precompute pattern?

Encodes user context (like login state) into hidden URL segments via proxy rewrite, enabling static rendering without cookies() calls.

Does precompute pattern hurt Next.js SEO?

No—browser URLs stay clean; search engines index the visible path.

Can I use precompute pattern with server actions?

Yes, but limit to static pages; actions remain dynamic by design.
