/* ============================================================================
   Yên Vân — bảng màu theo sắc tố tranh thuỷ mặc.
   Ba màu DỮ LIỆU (thạch lục · hoa thanh · chu sa) đã chạy qua bộ kiểm tra của
   dataviz ở cả hai chế độ: đúng dải sáng, đủ độ tươi, phân biệt được khi mù màu,
   và tương phản ≥3:1 với nền. Bốn màu cùng lúc thì KHÔNG qua nổi — nên nhóm
   "nội dung hụt" cố ý dùng mực trung tính thay vì màu thứ tư. Nó cũng đúng
   nghĩa: đó là trạng thái lưng chừng, không tốt cũng không hỏng.
   Vàng nhũ chỉ dùng cho nét trang trí, không bao giờ mã hoá dữ liệu.
