/*
  CIBN-PRESTISE, tampilan contoh (data dummy)

  Design Read: platform belajar dan ujian online untuk pelajar Indonesia,
  bahasa visual alam yang tenang (bukit, laut, awan) dengan warna dari logo merak,
  dial ENERGY 2 / RHYTHM 3 / MOTION 3.

  Alasan keputusan (R-31):
  - Warna: navy-teal, hijau daun, dan emas diambil langsung dari logo merak. Emas adalah satu-satunya aksen.
  - Huruf judul Fraunces: serif lembut dengan lengkung organik, sejalan dengan lekuk badan merak. Huruf isi Nunito Sans: hangat dan terbaca di layar kecil.
  - Sudut "daun" (dua sudut besar, dua kecil): satu bahasa bentuk untuk tombol, kartu, dan kolom isian, mengulang lengkung ekor merak. Bukan pil.
  - Motif identitas: garis lengkung emas tipis (dari lengkung di bawah kaki merak) sebagai pembatas dan garis bawah fokus.
  - Latar bukit dan laut fixed: permintaan pemilik, dan jadi satu-satunya "gambar" halaman, semua teks berada di atas panel kertas agar kontras aman.
