/* ============================================================
   Responsive — narrow phones (Galaxy Fold closed, iPhone SE/mini)
   At ≤380px the default 40px card padding ×2 = 80px leaves only
   240px of content, and the 4 OTP boxes at 50px each + 12px gaps
   need ~236px. Tight, but works. Below 380px the OTP boxes start
   to overflow. We tighten padding and shrink OTP boxes to keep
   the form tappable without horizontal scroll.
