/* ==========================================================
   Rakfolio — Gaya PANORAMIK
   Latar gelap sinematik, foto selebar layar.

   Ciri khasnya:
   - satu-satunya gaya berlatar GELAP: --rf-ink jadi warna terang
     (teks) dan --rf-paper jadi warna gelap (latar). Seluruh CSS tema
     ditulis mengikuti peran ini, jadi pembalikan cukup di sini saja.
   - hero setinggi layar dengan foto penuh dan gradasi di atasnya
   - karya TIDAK ditumpuk ke bawah, melainkan digeser menyamping
     dalam potongan 21:9 dengan judul menumpang di atas gambar
   - navigasi & keterangan huruf kapital berjarak lebar
