Google sign-in and account binding
Google sign-in requires binding first from an account you are already signed in to; an unbound Google account can neither sign in nor open an account. Order numbers on tracking links were unified at the same time, so your orders never expose our internal ones.
Your account centre now carries a Google card: while signed in, hit bind, approve on Google, and you land back done. From then on the Google button on the login page takes you straight into the console. Binding always comes first — an unbound Google account can neither sign in nor quietly open a new account, and one Google account binds to exactly one dealer account, with a clear message if it is already taken. Unbind from the account centre whenever you like; your password still works afterwards. The button appears on the overseas route only, as Google is unreachable on the mainland one. The same release also settled order numbers on tracking links into one fixed-length scrambled format that does not run in sequence, and fixed the earlier case where a new number suddenly grew two digits longer.
