/* ==========================================================================
   TND ASSURANCE — hệ thống giao diện và thành phần
   Kế hoạch: docs/KE-HOACH-THIET-KE-LAI-GIAO-DIEN.md (mục 6, 8)

   Giai đoạn chuyển tiếp: mọi class mang tiền tố `tnd2-`, quy tắc nền chỉ áp
   trong `.tnd2` để không va với site.css cũ. Khi 28 trang đã chuyển xong:
   xoá site.css, bỏ phạm vi `.tnd2`, đổi `tnd2-` → `tnd-`.
   Thứ tự: fonts → tokens → base → layout → components → utilities → print
