/* GIỎ DÙNG CHUNG (gio.js) — thanh giỏ dính đáy, bảng giỏ trượt từ đáy, nút + / − của thẻ món.
   Dùng ở cả trang chủ (/) và trang gọi món (/dat-mon): cùng màu, cùng font với web thương hiệu Bé Nếp.
   Biến riêng tiền tố --g- để không giẫm biến của từng trang. Không gradient, không kính mờ, không emoji. */
