/* ════════════════════════════════════════════════════════════════
   MOBILE.CSS v4 — Scale #wrapper (540px) as one unit
   Chiến lược: scale toàn bộ #wrapper từ top-center.
   #wheel-border-wrap (540px) + #wheel (500px centered by flex) +
   #shine, #spin, #border-svg đều scale cùng nhau.
   spinv1.js vẫn rotate #inner-wheel bình thường — không bị ảnh hưởng.
