/*
 * OJS 3.5 — Dark Blue / Light Content
 * Target: frontend Default Theme. Tema lain mungkin memakai selector berbeda.
 * Upload sebagai Journal style sheet di Settings > Website > Appearance.
 * HEADER: unggah banner melalui Logo pada pengaturan Appearance.
 * Rekomendasi banner: 1600 x 320 px; teks penting jangan terlalu kecil.
 * Opsi gambar latar: ubah --journal-header-image menjadi url("URL-ABSOLUT").
 * Gunakan URL absolut karena lokasi CSS unggahan ditentukan oleh OJS.
 * CSS tidak mengganti JavaScript/tombol navigasi bawaan OJS.
