    "note": "Median of 5 runs, darwin-arm64, `--spawn --prod` (PRODUCTION minified renderer, real boot — no fake-boot). Representative shipped numbers, not dev-inflated. cold-start reuses one profile so the V8 code cache is WARM (what users get after first launch, ~1.0s); a fresh-profile first launch is ~+400ms (measure with `--cold-fresh`). Marks are process-spawn wall clock (spawn_to_*) or renderer nav-relative (dom_*). Re-baseline per device with `--update-baseline`; tolerances loose for cross-machine/disk variance.",
