instant: deferred
The same data as the blocking tab, on the same short-stale probe-no-shell profile, but behind a <Suspense> boundary. The fallback is in the App Shell, so the navigation is instant even though the content is not.
"Instant" means the UI updates immediately. It does not mean every piece of content has arrived.
What to check
In dev, no insight for this tab. In a build, the tab switch paints immediately and you briefly see the fallback below before the panel replaces it.
Compare with the blocking tab, which renders this identical data with the boundary removed.

Still a shared cache entry, and still prerendered for a direct visit. It is not in the prefetched shell, so it arrives after the navigation instead of before it.
