/* Header + thanh khuyến mại + footer của TRANG CHỦ, dựng lại cho /guide/ (chèn bởi
   kidsafe-agent/landing/sync-to-kidsafe.ps1). Class tiền tố ksc- để không đụng CSS/JS của guide
   (guide có .header, .btn, .nav-link, #mainNav… riêng). Đơn vị px vì guide đặt html { font-size: 62.5% }.
   Giá trị khớp css/style.css của trang chủ — đổi một bên thì sửa bên kia. */
