Notes:

- Values are run medians across recorded runs. p95 and min/max are in the JSON.
- Backends are dispatched from inside the `kitesurf-bench` worker via RPC bindings: `env.KITESURF.fetch(/screenshot|/html)` for kitesurf (service binding to the engine), `env.BROWSER.quickAction('screenshot'|'content', …)` for browser-run (Browser Rendering RPC), and `env.CONTAINER_HOST.fetch(…)` for container (sibling worker fronting its container backend). Wall time is the orchestrator's `performance.now()` span; `backendWallMs` / `backendCpuMs` in the JSON come from Workers Observability (kitesurf) or container-side timing headers (container). None of the measurement paths traverse the public internet.
- A cell shows `—` when every recorded run for that combination errored. See `rows` in the JSON for individual failure messages.
