/* Scan a UPI QR (upi-scan.js): a scanner card with the camera and a framed viewfinder, a result card with the payee and
   the UPI ID large enough to read across a counter, and the recent codes kept on this phone. The cards are .card, so the
   workspace's glass applies; everything here is layout and the pieces that are this page's own. */
