- Eval works on Lightpanda when called with go-rod's expected function
form (e.g. "() => document.title"); only bare expressions fail, and
they fail on Chrome too. Fix the integration gap test and docs that
incorrectly attributed this to a Lightpanda bug.
- docker-compose.lightpanda.yml: add the missing
command: lightpanda serve ... — the image's entrypoint isn't
lightpanda, so without an explicit command the sidecar wouldn't
start.
- docker-compose.lightpanda.yml: opt-in overlay running
lightpanda/browser:latest, wires GOCLAW_BROWSER_REMOTE_URL and
GOCLAW_BROWSER_BACKEND so the manager picks the right code path.
- docs/browser-backends.md: compatibility matrix vs Chrome (screenshot,
multi-tab, cookie sharing, etc.) and guidance on when to pick which.
