label property
The ZIP-321 label display field (a name the requester attached to the
address), when the request came from a URI. Carried for the host's use —
deliberately NOT auto-rendered by the send form: it is an
attacker-controllable string from an untrusted QR/link (a phishing
surface), so the host, which alone has trusted context (e.g. the contact
it resolved), decides whether/how to show it. null for a typed request.
Implementation
final String? label;
