   ATLAS RESEARCH — Trang chủ "Quỹ đạo Atlas" (chỉ index.html nạp file này)
   -----------------------------------------------------------------------------
   Kiểu tạp chí cao cấp trên một nền giấy duy nhất: không khối màu chia đoạn, không
   scroll-snap. Vòng quỹ đạo vàng của logo là sân khấu SVG cố định (js/home.js vẽ)
   đi xuyên cả trang. Tiêu đề Newsreader (có chân), chữ thân Be Vietnam Pro.
   style.css (dùng chung mọi trang) nạp trước; file này chỉ thêm/ghi đè cho trang chủ.
   ----------------------------------------------------------------------------
   1. Token            4. Bốn sàn            7. Kết trang (colophon)
   2. Nền + quỹ đạo    5. Khoảng lặng        8. Bản đồ vị trí
   3. Hero + bàn tin   6. Kiểm tra + ví      9. Responsive, giảm chuyển động, in
