/**
 * A recurring invoice as the admin API publishes it.
 *
 * A recurring invoice is a schedule plus a template of a document, so the
 * payload opens with the scheduling half -- when it starts, when it fires next,
 * the cron frequency, how it is limited and whether generated invoices go out
 * on their own, each key date also rendered in the company's date format -- and
 * continues with the template half, the same amounts and flags an invoice
 * carries.
 *
 * The related records are each gated behind an existence probe on the relation,
 * including `invoices`, which publishes the documents this schedule has already
 * produced through the invoice resource itself.
