/* ===================================================================
   Cakrawala Sign — stylesheet utama
   -------------------------------------------------------------------
   Sistem desain:
   - Warna  : navy (--primary-color) sebagai warna utama, emas
              (--secondary-color) hanya sebagai aksen dan tombol utama.
   - Tipografi : Archivo (judul) + Source Sans 3 (isi teks). Dua keluarga
              font, empat ketebalan.
   - Spasi  : skala 4pt (--space-1 = 4px).
   - Semua nilai warna dan font memakai variabel. Jangan menulis hex
     langsung di dalam rule — tambahkan variabel baru bila perlu.

   Urutan isi file:
   1. Token         6. Header & navigasi   11. Portofolio
   2. Reset & base  7. Hero                12. FAQ
   3. Layout        8. Layanan             13. CTA & footer
   4. Tipografi     9. Keunggulan          14. Formulir
   5. Tombol       10. Proses              15. Halaman dalam & responsif
