   TCN TRADING — style.css  (bản 2, 19/09/2026)

   Viết lại sạch sau khi đo hệ thống thị giác của các landing EA
   đang chạy tốt. Bốn thứ tạo nên khác biệt, đo được chứ không đoán:

     1. Vàng là GRADIENT KIM LOẠI nhiều điểm dừng, không phải màu phẳng
     2. Tiêu đề dùng font NẶNG (800–900) + letter-spacing âm
     3. Nền có LỚP: lưới mờ + vầng sáng radial, không đơn sắc
     4. Card bo GÓC TO + bóng đổ SÂU, không phẳng lì

   Sửa màu: đổi ở :root. Sửa vàng kim loại: đổi --gold-metal.
   ============================================================ */
