  19   * A script to display a ReCaptcha for the site.
  20   *
  21   * ReCaptcha V2 is restricted by domain, so it cannot be displayed in mobile and desktop apps.
  22   *
  23   * This script will display and initialize the reCaptcha, setting some empty callbacks by default. The client can override
  24   * those Javascript callbacks (in the "window" object).
  25   *
  26   * This script won't work in mobile and desktop apps unless $CFG->allowframembedding is enabled.
