   - Hanya gerakan (transform/opacity/filter/background-position).
   - TIDAK mengubah warna, ukuran, posisi, grid, font, atau spasi.
   - Token warna yang dipakai hanya token yang sudah ada di :root.
   - Semua animation/transition dinetralkan oleh blok

   Aman untuk dihapus: hapus seluruh blok ini -> kembali ke animasi
