   SAINT INTELLIGENCE | main stylesheet (v3)
   Mobile first. Navy = warna utama, putih = warna kedua,
   aksen = putih di latar navy, navy di section terang. Hijau WhatsApp cuma di dalam mockup chat.
   Warna komponen diatur lewat variabel per permukaan:
   default navy, section terang pakai .on-light (maks 3 per halaman).
