Notes:

- Values are run medians across recorded runs. p95 and min/max are in the JSON.
- Both backends are invoked from inside the same Cloudflare worker (`packages/bench-report`) via RPC bindings: `env.KITESURF.fetch(/screenshot|/html)` and `env.BROWSER.quickAction('screenshot'|'content', …)`. Wall time is measured around a single `performance.now()` span on each side — no inter-machine network in the measurement.
- A cell shows `—` when every recorded run for that combination errored. See `rows` in the JSON for individual failure messages.
