  PERPUSTAKAAN ANIMASI GRADASI - EDUKREIN
============================================== */

/* CATATAN PENTING:
  - Sebagian besar animasi ini menggunakan variabel warna dari template Anda 
    (misal: var(--ds-blue), var(--ds-green), dll).
  - Anda bisa mengatur kecepatan dengan mengubah nilai `animation-duration`.
  - Gunakan efek ini secara bijak agar tidak memberatkan loading blog.
