Launches a real browser via browser-use, loads the probe page with a session_id,
clicks the First National card, fills+submits the summary box, then verifies the
attacker event log recorded the behaviour. This validates the entire
browser -> server -> telemetry -> event-log loop independently of any LLM.
Requires the attacker server running on its port (scripts/serve.sh).
Usage: uv run python scripts/browser_check.py
