/**
 * The five report controllers are the only callers of ->download(), and
 * GotenbergPdfResponse never had that method. Selecting the Gotenberg driver
 * therefore turned every report download into a fatal undefined-method error,
 * while the same page streamed fine. Nothing caught it because the factory
 * returned the vendor dompdf wrapper for one driver and a bespoke class for the
 * other, with no shared type between them.
 *
 * These run against dompdf so they need no Gotenberg service; the contract that
 * keeps the two in step is asserted in tests/Unit/PdfDriverContractTest.php.
