   09-OTP-MODAL.CSS — Al Aliyah Supermarket implementation kit
   Status: PENDING REVIEW.

   The generic `.aly-modal` scaffold lives here because the OTP sign-in
   popup is this kit's primary/reference modal, but the scaffold itself is
   reusable for any dialog (address-edit, confirm-remove, etc.) — see
   js/otp-modal.js for the paired behaviour (focus trap, Escape, etc.).
