/* =====================================================================
   GARAZ UI · bộ giao diện dùng chung · v1.0
   ---------------------------------------------------------------------
   1. Token (màu, chữ, kích thước) — sửa ở đây để đổi thương hiệu
   2. Nền tảng (reset, chữ, focus)
   3. Khung ứng dụng (sidebar, thanh trên, trang)
   4. Thành phần (nút, ô nhập, lựa chọn, công tắc, thẻ, bảng, nhãn trạng thái,
      thông báo, tab, hộp thoại, menu, phân trang, dòng thời gian…)
   5. Khuôn màn (danh sách, form, hồ sơ, chứng từ)
   6. Tiện ích
   Ô nhập/chọn được style theo thẻ HTML, nên form Django render mặc định
   dùng được ngay, không cần thêm class cho widget.
