/* What: the create-account page (/register), shaped like the certificate it leads to: the emerald proof panel at the start (the
         title, the certificate's pearl side in small with the name filling in, what comes next, the way to sign in) and a pearl
         sheet beside it holding the form - named sections, 48 px fields, choice tiles, the photo window, one gold button.
         A workshop's registration (/w/{slug}/register, .signup.reg) is the same page with the workshop in the panel: its name,
         its dates, its sales tag, and the certificate naming it.
   Use: linked by Accounts/views/signup.php and Registrations/views/register.php; js/signup.js fills the certificate and runs the
        eyes and the photo zones.
   Needs: tokens.css and app.css (.field, .input, .form-grid, .btn-gold, .eyebrow, .alert); img/spine-lines.svg; logical properties
          only, so the page mirrors itself in Arabic (spec 11.3). */
