   RESPONSIVE DESKTOP
   Di layar >= 900px, halaman USER (phone-frame) berhenti
   dipaksa selebar HP: jadi kartu terpusat dengan lebar wajar,
   nav bawah disembunyikan & diganti nav atas horizontal,
   grid konten melebar mengikuti ruang yang tersedia.

/* =========================================================
   RESPONSIVE DESKTOP
   Mobile (default di atas) TIDAK berubah sama sekali.
   Di layar >= 900px, halaman USER berubah jadi tampilan desktop
   yang lega: lebar mengikuti layar (maks 1100px), nav pindah ke
   atas (jadi seperti navbar web biasa), grid melebar lebih banyak
   kolom supaya tidak terasa sempit/dipaksa seperti HP.
