   1VONG — Trang chủ hệ sinh thái (bản mẫu cho 1vong.com)
   PHÂN CẤP THEO GIÁ TRỊ (chủ dự án chốt): không dàn hàng đều "lợn cả đàn".
   · Bốn trụ mệnh lý  — Tử Vi (nổi bật nhất) + Bát Tự · Phong Thủy · Lịch
   · Gieo quẻ hỏi việc — Kinh Dịch (dẫn đầu) + Mai Hoa · Lục Nhâm · Kỳ Môn
   · Huyền học Tây phương — Tarot (dẫn đầu) + Chiêm Tinh · Thần Số · Bói Bài
   Mỗi nhóm: MỘT thẻ nổi (giá trị hiện rõ) + ba thẻ chuẩn. Giá trị mỗi môn
   hiện ngay trên thẻ (không cần bấm). Bấm = xem sâu thêm.
   Một gốc thương hiệu (nền đồng thau chung) — nhiều bản sắc (con dấu màu riêng).
   Tiêu đề Cormorant · nội dung Be Vietnam Pro.

   Hai lỗi thật:
   1. Khi chủ dự án gán menu trong quản trị, wp_nav_menu in ra <li><a> chứ
      không phải <a> trần — mà CSS chỉ nhắm .foot-col a, nên hiện ra dấu chấm
      đầu dòng và các mục dính vào nhau. Nay nhắm cả hai kiểu.
   2. Cột "Pháp lý" chứa "Tuyên bố miễn trừ trách nhiệm" — cụm dài nhất — mà
      lại hẹp bằng các cột khác, nên xuống ba dòng, đọc ra như chữ vỡ vụn. */
