/* ==========================================================================
   ETALASE BUKU — layar pertama + banner sneak-peek
   Sumber data & render: assets/js/etalase.js

   TEMA: putih + pink simple, mengikuti fashtrek.com asli.
   TIPOGRAFI (arahan 31 Agt): profesional, langsing, mudah terbaca —
   Manrope 500–700 untuk semua teks etalase; Syne yang gemuk-lebar tidak
   dipakai di sini. Ukuran kecil, ruang kosong yang bekerja.

   REVISI 2 Sep:
     1. Sampul belakang & punggung buku 3D KRIM, sewarna sampul depan —
        bukan arang. Buku tidak lagi berubah warna di tengah putaran.
     2. Panah kiri/kanan di tiga tempat: panggung, rel daftar buku, dan
        sneak-peek. Gerak otomatis tetap jalan, tapi selalu bisa dikemudikan.
     3. Rel daftar buku dibesarkan jadi KARTU — sampul 92px yang jelas
        berbentuk buku (punggung + blok kertas 3D), plus penjelasan singkat.
     4. Semua teks penjelas EFEK dihapus ("berputar 360°", "membalik
        sendiri", "arahkan kursor"). Yang tersisa hanya informasi buku.

   Dua lembar, satu per arah:
     .pk-leaf-fwd   paruh kanan, engsel kiri,  0 → -180°  (maju)
     .pk-leaf-back  paruh kiri,  engsel kanan, 0 → +180°  (mundur)

   Lembar maju juga yang memainkan "buku terbuka": ia mulai dari -180°
   (menutupi paruh kiri, memperlihatkan sampul di muka belakangnya) lalu
   terayun ke 0°. Satu transisi, dipakai ulang — tidak ada animasi kedua
   yang harus disinkronkan.
