pip-installable Python API driving the bundled binary over MCP HTTP: Browser/Session with one generated method per browser tool (lightpanda/_methods.py, regenerated from tools/list), run_script() replay, a CLI trampoline entry point, pytest suite against local fixtures, and pdoc docs generation.
Browser(args=[...]) forwards flags like --http-cache-dir to the spawned lightpanda mcp process; needed by the pandascript-vs-cdp benchmark leg and useful for cookies/robots flags generally.
PR_SET_PDEATHSIG on the spawned lightpanda mcp process (Linux) so a SIGKILLed or crashed interpreter cannot leak a browser process — a 2h44m orphan surfaced during the v6 benchmark campaign. Regression test kills a parent and asserts the sidecar exits.
