 creates a pending bind session. Final binding is completed after the device
 returns an NFC card UUID.

+This is the user/NFC binding flow and is separate from the device-level
+`msg_id=012` bootstrap/binding handshake documented in
+`02-device-bootstrap.md`. The `msg_id=012` success receipt assigns the device
+identity and returns `iccid`; this flow binds that device to a mini-program
+user and optional child through the NFC card exchange.
