I know it is all our playground, but do we happen to have some url-building
library (instead of simple concatenation?

I am not aware of any. We have GURL in C++ but nothing I know of in JS.

       this.signInUrl_ = url;
       var modes = ['manual', 'forced', 'auto'];
       for (var i = 0; i < modes.length; ++i) {
         this.classList.toggle('mode-' + modes[i],
                               data.enrollment_mode == modes[i]);
       }
       this.managementDomain_ = data.management_domain;
       $('oauth-enroll-signin-frame').contentWindow.location.href =
           this.signInUrl_;
       this.updateLocalizedContent();
