   Affiliate By DuongPT — hệ thiết kế theo shadcn/ui (zinc base, "new-york")
   Nguồn thiết kế: docs/ui_shadcn_mockup.html — sửa CSS ở đây phải soi lại file đó.

   Nguyên tắc: nền trắng · viền mảnh 1px · radius 8px · chữ 14px ·
   KHÔNG gradient · KHÔNG glow · bóng đổ gần như không thấy.

   ⚠️ KHÔNG còn Pico CSS. File này tự lo mọi thẻ HTML. Cuối file có
   "LỚP TƯƠNG THÍCH" dịch markup thời-Pico (role="button", .outline, <article>,
   var(--pico-*)…) sang hệ mới — 26 template chưa kịp viết lại vẫn hiển thị đúng.
   Dọn dần từng trang thì xoá dần phần đó, ĐỪNG xoá cả cụm một lúc.

   ⚠️ Sửa file này → BUMP `?v=` trong base.html + login.html, nếu không trình
   duyệt giữ CSS cũ và chủ sẽ "không thấy thay đổi".
