feat: canvas fingerprint noise + stealth patches#27
Merged
Conversation
…x headless fix Three stealth improvements: 1. Canvas fingerprint randomization: inject per-session noise into toDataURL()/toBlob() readback so each session has a unique canvas fingerprint. Defeats PerimeterX/DataDome static fingerprint matching. 2. Expanded permissions API patch: cover geolocation, camera, microphone, payment-handler in addition to notifications. Bots commonly miss these, triggering detection heuristics. 3. Fix persistent context headless bug: was hardcoded to false instead of using launchPlan.headless. Now respects profile/CLI setting.
