 Donors see only their own receipts, and only once **confirmed**. Confirming
 a receipt in the back office is therefore what publishes it.
 
+A download button is shown only when the PDF can actually be rendered: a

 * **No archiving.** The PDF is rendered at each download and never stored.
   A receipt whose rendering becomes impossible (report deleted or
