/* اجتماعی امتحانات — template-exam-registration.php.
   Stepper, radio, summary, success and confirm rules are copied from
   admission.css and renamed (that wizard is dormant; nothing is shared).
   Every rule that gives a state-toggled element `display: X` is paired
   with its own `[hidden] { display: none; }` guard, as in admission.css.
   Rules for controls inside the form are prefixed `.exam-form` so they
   outrank style.css's `.field label` / `.field input` (0,1,1), which
   would otherwise make every radio, checkbox and file input a
   full-width 48px text control. */
