Measuring network conditions — RTT to edge, throughput curve, protocol detection. This establishes the speed-of-light floor for all metrics.

3 warmup visits (discarded) then 5 measured navigations with persistent context. Session tickets and cache active — simulates a returning visitor.

5 navigations each in a fresh browser context. No cache, no session tickets, full TLS handshake — simulates a first-time visitor.

Computing p50/p75/p95 statistics, LCP decomposition, physical limits efficiency, and optimization opportunities.
