"""Open a visible browser at y.qq.com so the user can manually verify
whether their VIP account can play 稻香 (Jay Chou) in the real QQ Music
web player.

If the browser plays the song → entitlement exists and our 104003 is a
request-signing issue.
If the browser refuses / shows a VIP modal / silently fails → the
account doesn't have entitlement OR QQ's web player hits the same wall.
