/* =============================================================================
   BỘ CSS RIÊNG CHO MODULE CHỨNG TỪ KẾ TOÁN (ct-*)
   Dùng cho các trang danh sách + nhập liệu chứng từ (ChungTuKeToan/ChungTuDoanhNghiep)
   và các control dùng chung của chúng (FormField, DateField, MoneyField,
   AccountComboBox, FormSection, VoucherListShell, VoucherPaper...).

   Mọi trang/control chứng từ nên bọc trong 1 phần tử gốc có class "ct-page" để
   nhận đúng biến màu/khoảng cách bên dưới, thay vì rải chuỗi tiện ích Tailwind
   trực tiếp trong markup — sửa 1 chỗ ở đây là đổi đồng loạt.
