 *
 * Override by copying to {theme}/easy-invoice/document/single.php.
 *
 * Variables available to overrides:
 *   $document_type  'invoice' | 'quote'
 *   $document       The model
 *   $invoice        Same object when it is an invoice, else null
 *   $quote          Same object when it is a quote, else null
 *   $formatter      Currency formatter for this document
 *   $text_settings  Button labels from Settings → Text
