/* ===== K1 · Bàn xoay thực đơn =====
   Giao diện theo bản vẽ Claude Design 20/10/2026: bàn tròn hiện trọn, 4 đĩa quanh đĩa kính ở giữa,
   khẩu hiệu bên trái, Chép bên phải (PC). Cơ chế bàn quay / đĩa bay lấy từ mẫu "La Table" (đã xin phép).
   Tên class mà ban-xoay.js dùng (plate-position, dish-card, menu-outgoing, lifted, forming…) giữ nguyên. */
