       form input, btn-submit, alert, auth-foot, dst.)
     • Mobile gate @media (max-width: 768px) yang strip animasi
       paling berat (filter blur besar, backdrop-filter, animasi
       infinite) supaya halaman ringan di HP. Visual desktop tetap
       utuh.

   MOBILE GATE — Strip animasi paling berat di HP
   ------------------------------------------------------------
   Target: HP & tablet kecil (≤ 768px) di mana mobile GPU
   kewalahan dengan filter blur besar + backdrop-filter + banyak
   layer compositor aktif. Visual desktop TIDAK terpengaruh.

   Strategi:
   • HIDE total — elemen dengan blur radius besar / sangat lebar:
       glow-tr, glow-bl, dawn-arch, constellation
   • DISABLE animation tapi tetap visible — visual heritage tetap
     terasa, cuma tidak bergerak:
       heritage-grid, arabesque-rings
   • REDUCE jumlah — lentera 7→2, partikel 10→3, dan kecilkan
     box-shadow lentera supaya compositor lebih ringan.
   • REPLACE backdrop-filter dengan solid background — backdrop
     blur adalah salah satu operation termahal di mobile Safari/
     Chrome, harus re-sample tiap repaint.
   • DISABLE animasi kecil yang sering trigger compositor
     (scan-line card, sheen tombol, halo logo kedua).
