   Bucin4D Peduli HIV — stylesheet
   Arah desain mengikuti hiv.gov: bilah sian di paling atas, header putih,
   bilah remah navigasi abu arang selebar layar, dua kolom (sidebar daftar
   isi + kartu artikel), judul dan teks bodi serif, lencana bulat melayang.

   Kedalaman dibangun dari bayangan abu netral, sudut membulat, dan garis
   tepi — bukan dari gradasi atau cahaya berwarna.

   Semua blok isi memakai .container yang sama, termasuk hero, supaya
   tepi kiri-kanannya segaris dari atas sampai bawah.

   1. Token       5. Hero          9. Kartu & daftar
   2. Reset       6. Dua kolom    10. Footer
   3. Dasar       7. Prosa        11. Formulir
   4. Header      8. Bagian       12. Responsif
