/* Minda Ceria · Buku Cerita. Lapisan skrin penuh dalam app: tiada bar tab / rel sisi.
   Owner 27 Okt: DESIGN 5 "Timbun Kad".
   - Rak: kulit buku bertimbun (sebelah kiri/kanan senget di belakang), statistik anak, butang Baca besar.
   - Pembaca: kad putih bertimbun (gambar/video 3:2 + ayat + cip perkataan), bar kemajuan, butang lampu.
   - Lampu hidup = cerah (lavender); lampu tutup = mod gelap untuk baca dalam gelap (navy).
   - Atas setiap skrin: gradien dari krim bar status (#fff6ea) ke warna latar, sama seperti preloader/lendir app.
   - Tukar halaman: kad atas melayang keluar, kad bawah naik dari timbunan (tiada lendir).
   - Masuk/keluar rak + buka/tutup buku: lendir titis (bulat dari titik tekan, kemudian meleleh ke bawah).
   - Bar status TIDAK diubah (owner: "Aku x suruh tukar bar punya setting dan color"). Butang rata, tiada bayang. */
