/**
 * Conversation between the sender and the recipient the form was delivered to. Only populated when the form was dispatched via `POST /forms/send` with a `to` recipient — that's the only call that opens a conversation tied to a form submission.
 *
 * Null in every other case, including:
 * - `POST /forms/send` without a `to` (URL-only mints — no message is sent, so no conversation exists).
 * - Submissions to a form whose URL was shared by any other means (e.g. an RCS card built with `POST /send`, a chat message, a marketing email, or a link on your site). The recipient isn't tied to a Pinnacle conversation in those flows.
