/* =========================================================================
   ASI Universal Auth Modal

   Trigger from anywhere (header user icon, wishlist heart, future CTAs)
   via data-asi-auth-open or window.asiAuth.open(). Three states inside
   one sheet:

     • Form (login OR signup)  — the default body
     • Success                 — replaces body after a successful signup
     • Loading                 — overlay on the submit button

   Mobile bottom-sheet, desktop centered card. Same animation grammar
   as the rest of the storefront (cubic-bezier(0.22, 1, 0.36, 1)).
