   Sigma Academy — landing page

   Struktur, demo dan mesin halaman sama persis dengan partners/wargaritel.
   Yang berbeda hanya rupa: warna, font dan bentuk meniru sigmaacademy.id
   (hijau-hitam, aksen emerald, Inter tebal, navbar pil berpendar, kartu
   kaca, teks gradien bergerak). Warna di bagian 1-8 sudah diganti dari
   oranye ke emerald; bentuk khas Sigma ada di bagian 9 di bawah.

   Mockup Mini App memakai token --ma-* yang ikut dihijaukan supaya
   menyatu dengan halaman.

   Lapisan file ini:
     1. Token & dasar        5. Daftar fitur
     2. Header & jam bursa   6. Kerangka section fitur + stage demo
     3. Hero & pipeline      7. Ponsel, Telegram, Mini App
     4. Pita ticker          8. Jadwal, FAQ, CTA, footer
                             9. Lapisan Sigma Academy
