/* ==========================================================================
   Prime Generation — Landing Page
   SISTEM WARNA SATU-HUE ("Premium Depth").

   !!! PERINGATAN !!!  --brand-2 SENGAJA TIDAK DIPAKAI SATU KALI PUN.
   Di produksi --brand-2 == --brand, sehingga setiap gradient "brand -> brand-2"
   tampil DATAR tanpa error apa pun (gejalanya senyap). Semua kedalaman warna
   diturunkan dari var(--brand) lewat color-mix()/oklch(). JANGAN menambahkan
   var(--brand-2) kembali ke file ini.

   Struktur:
     1. Token warna (3 lapis) + alias ber-scope
     2. Tipografi, spacing, bayangan
     3. Dasar & utilitas
     4. Komponen per-section
     5. Animasi (keyframes)
     6. Responsif
     7. prefers-reduced-motion + print
