Pre-launch checks

After launching a profile, verify on BrowserLeaks and FingerprintJS Demo:

Check	Expected
IP / timezone / language	Match proxy egress and profile settings
WebRTC	No leak of real LAN or public IP
Canvas / WebGL / Audio	Differs from baseline; stable per profile
UA vs resolution	Consistent with chosen OS
Geolocation	Matches IP region when IP auto-match is on

If something fails, see Fingerprint reference and Troubleshooting.
