 The "before" numbers show a server under severe stress: 25% of requests failed (likely timeouts), and p90/p95 hit the 10s timeout ceiling. After the optimizations, the server handles the same load comfortably with sub-30ms tail latency and zero failures.
 
-To be clear: TanStack Router was not broken before these changes. Under normal traffic, SSR worked fine. These numbers reflect behavior under *sustained heavy load*—the kind you see during traffic spikes or load testing. The optimizations ensure the server degrades gracefully instead of falling over.
