### What?
Added a new section "Opting Into Fully Dynamic Rendering" to
`errors/blocking-route.mdx`.
### Why?
To surface the "Suspense over body" pattern as a general solution for
"Uncached data or connection() was accessed outside of <Suspense>"
errors. This pattern was previously only documented in
`next-prerender-dynamic-viewport.mdx` but is relevant to all blocking
route errors, providing a clear opt-out for users who want fully dynamic
rendering without granular Suspense boundaries. This directly addresses
a common user query.
### How?
Added a new section with a code example demonstrating wrapping the root
`<html>` in `<Suspense>` within `app/layout.tsx`.
