/* LearnGeo 2026 - dark theme, zinc base + satu aksen sky.
   KEPUTUSAN DESAIN (satu baris per keputusan):
   - Gelap: game kuis dan peta dibaca paling nyaman di latar gelap, dimainkan malam hari.
   - Satu aksen (sky #38bdf8): hanya untuk aksi primer dan penanda aktif, sisanya netral zinc.
   - Tanpa gradien warna: gradien biru-ungu adalah pola generik, diganti warna solid.
   - Plus Jakarta Sans satu-satunya typeface, termasuk tombol dan input (button/input tidak mewarisi font body secara default, jadi dipaksa font:inherit). Hierarki cukup dari ukuran dan ketebalan.
   - Radius 10-16px sebagai sistem: tombol dan input 10px, kartu 12-16px, bukan semua pil.
   - Bayangan hanya sebagai elevasi: kartu dan modal menempel, hanya tombol primer yang sedikit terangkat.
   - Kartu Tebak Negara full-width: itu game inti, pantas dapat porsi lebih dari dua mode pendukung.
   - Warna-warni hanya di peta: tiap benua perlu warna beda agar terbaca (data, bukan dekorasi).
   - Gerak hanya transisi antar-layar dan confetti sekali saat menang, tanpa loop tanpa akhir.
   Dial: ENERGY 2 / RHYTHM 2 / MOTION 2. */
