start_session
Start a Playwright Chromium session for automated testing or demo video creation. Optionally record WebM video with narration and reuse authentication profiles.
Instructions

Optional recordVideoPath enables WebM capture at 1920×1080 @ deviceScaleFactor 2 with synthetic cursor and always-on click highlight. When recording, demoMode is on (narrate defaults true): orchestrate auto-paces to TTS. Pass profileId from login or set_session_auth to reuse auth.
