misc::QrCodeScanner reads QR codes with rqrr 0.11 from the frames the host hands in, one at a time off the main thread, and hands each code to the owner once. misc::Captcha shows the owner's picture over an answer field that empties and keeps focus with each answer; the owner says how it stood. BarcodeDisplay, Signature and Rating Widget point to their homes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
