 * Halaman masuk berpanel dua.

 * Dipisah dari pos.css karena hanya dipakai satu halaman, dan halaman itu
 * justru yang paling sering jadi kesan pertama. CSS biasa, ikut di-commit,
 * tanpa langkah build — lihat alasannya di README.
 *
 * Panel kanan hanya menyediakan wadah; isinya formulir Filament apa adanya,
 * jadi gaya di sini sengaja tidak menyentuh bagian dalam formulir supaya
 * pembaruan Filament tidak pernah merusak tampilannya.
