/* =============================================================================
   onboarding.css — Hướng dẫn animation (đăng ký · đăng nhập · kết nối Zalo / OA / Facebook)
   -----------------------------------------------------------------------------
   Phần 1: khung trình phát   (.ob-root, .ob-card, .ob-head, .ob-body, .ob-cap, .ob-foot …)
   Phần 2: gạch dựng cảnh     (.ob-type .ob-show .ob-win .ob-field .ob-btn .ob-toast .ob-check .ob-ico .ob-qr .ob-phone)
   Phần 3: nút mở hướng dẫn   (.ob-launch — dùng ở trang đăng nhập, trang chủ, hộp thêm kênh …)
   CSS riêng từng cảnh: scenes/<id>.css (nạp khi cảnh được mở). Mọi lớp / keyframes đều tiền tố "ob" để không đụng CSS cũ.
   Quy ước animation: chỉ đổi opacity / translate / scale (chạy trên GPU); dùng thuộc tính riêng `translate` / `scale`
   (không dùng `transform`) để không ghi đè transform tác giả đặt cho phần tử.
