 * The PDF routes bind on unique_hash (`/invoices/pdf/{invoice:unique_hash}`), and
 * the seeder builds its documents with Model::create() rather than through the
 * service layer that normally assigns it. When that was missed, every seeded
 * document produced a `/invoices/pdf/` URL with an empty segment — a 404, surfaced
 * in the UI only as "Unable to load document preview", with nothing in the log.
 *
 * Anything the seeder creates that the app then serves by hash has to carry one.
