 * File Name: email_broadcast_recipient.mdl.js
 * Type of Program: Model
 * Description: The outbox — one row per recipient of an email_broadcasts job.
 *              `email` is snapshotted at enqueue time so a later change to the
 *              user's account email doesn't affect an in-flight broadcast.
 *              cron/jobs/dispatch_email_broadcasts.cron.js is the only writer
 *              of `status`/`error`/`sent_at` after creation.
