qrcode-generator 1.4.4 (https://github.com/kazuhikoarase/qrcode-generator)
Copyright (c) 2009 Kazuhiko Arase — MIT licensed, GPL-compatible.

Vendored so QR codes are generated in the browser, offline, with no third-party
service and no server-side image library. HopWise draws the module matrix onto a
canvas in assets/js/admin.js, which also produces the PNG download.

Unmodified.
