/* =========================================
   REVEAL GATING — chờ bấm "enter" mới chạy animation
   Mặc định: mọi animation reveal của profile-card, avatar,
   scroll-cue, intro-rail... bị PAUSE ngay từ khung hình đầu
   (nhờ animation-fill-mode: both/from state), nên chúng đứng
   yên ở trạng thái "ẩn" cho tới khi có class .is-entered.

   JS chỉ cần thêm class "is-entered" vào <body> khi user
   bấm .entry-button — animation sẽ tự resume và chạy đúng
   theo delay đã khai báo (không cần đụng vào các @keyframes
   hay giá trị delay ở trên).
