+Taking the example of the `useRouterState` hook, we can see that most of the client-only work was removed from the SSR pass, leading to a ~2x improvement in the total CPU time of this hook.

-## Fill-in checklist before publishing
-
-- [x] Replace throughput placeholders with final numbers.
-- [x] Replace latency placeholders (avg/p90/p95) with final numbers.
-- [ ] Insert flamegraph screenshots and annotate the "before" hotspots and "after" removal.
-- [ ] Ensure every external claim has a citation and every internal claim has evidence.
-- [ ] Add `layouts-26-with-params` benchmark results (if desired).
