/* Giao diện mới — bám theo bộ thiết kế 5 màn.
   Độc lập hoàn toàn với css trang cũ nên hai giao diện không giẫm cascade nhau.

   ─── MÀU ───────────────────────────────────────────────────────────────────
   Mọi màu đi qua biến. `:root` là bảng TỐI (mặc định của sản phẩm), còn
   `[data-theme="light"]` ghi đè sang bảng SÁNG.

   Chủ đề do một script inline trong <head> đặt TRƯỚC khi CSS vẽ — nếu để JS
   thường đặt sau khi tải xong thì người dùng thấy một nháy màu tối rồi mới đổi
   sang sáng, rất khó chịu ở lần mở trang đầu.

   Token gom theo VAI TRÒ chứ không theo giá trị: ở bảng tối `--surface` và
   `--surface-3` gần giống nhau, nhưng ở bảng sáng một cái trắng, một cái xám
   nhạt — tách ra mới chỉnh riêng được.                                        */
