One isolated Android passkey test

Test origin: https://passkey-check.jhona-core.com
RP ID: passkey-check.jhona-core.com

No owner enrollment. Use Windows Chrome and select your Redmi phone through QR. One test entry may synchronize through Google Password Manager. Do not retry or create another credential after a stop.

I am the owner and authorize this one test using my Redmi phone, not Windows Hello or a desktop-only provider.
