  Desain: "Perpustakaan Digital ABBA" — rak lima jilid NALAR KEADILAN.

  Token sistem:
    Warna dasar : --paper #FAF7F0 (kertas hangat, bukan putih steril)
                  --ink    #1B3A57 (biru tua institusional, dari sampul buku)
                  --gold   #C8860D (emas redup, aksen "percaya diri")
                  --line   #DDD3BE (garis pemisah hangat)
    Warna jilid : ditentukan per-buku di config.php (properti 'warna'),
                  dipakai sebagai aksen "punggung buku" di rak.
    Tipografi   : display = Lora (serif, berwibawa, kesan kitab)
                  body    = "Source Sans 3" / system sans (mudah dibaca lama)
    Layout      : dashboard = rak buku horizontal/grid, bukan kartu generik.
