/*
 * Typing Practice Pro - certificate.
 *
 * Kept in its own file because the certificate appears on the certificates
 * page, inside the [typing_certificate] shortcode and in the result screen -
 * none of which reliably load the typing workspace stylesheet. See print.css
 * for the printed layout, which is the form most people will actually see.

/* ==========================================================================
   Certificate
   ==========================================================================
   Designed to be printed. The scores are rendered as keycaps because that is
   the one motif unmistakably tied to a typing site, and it survives being
   reduced to black and white on a home printer. Colours are set with
   print-color-adjust so browsers do not strip the brand fills.
