/* ============================================================
   AL GÖTÜR — Fizibilite Sunumu · styles.css
   TASARIM YÖNÜ (3 karar):
   1) "Karar odaklı koyu salon" estetiği: koyu lacivert/antrasit zemin
      (#10141d–#1c2434) üzerinde sıcak kırık beyaz metin (#f3eee4).
      Sunum bir satış pitch'i değil, karar toplantısıdır; bu yüzden
      ciddi, sakin, düşük doygunluklu bir palet seçildi.
   2) Anlam renkleri sabit sözlük: doğal yeşil = güven/mevcut/doğrulandı,
      sıcak turuncu = topluluk/vurgu, kırmızı = risk/olumsuz gerçek,
      nötr griler = harita/veri dokusu. Her renk tek anlam taşır.
   3) Veri önce, dekorasyon sonra: tüm görseller CSS/SVG ile üretildi
      (harita mockup'ı, skor çubukları, projeksiyon grafiği, risk
      matrisi); stok fotoğraf, gradient şovu ve gereksiz animasyon yok.
      Kontrastlar WCAG AA hedefli (metin ≥4.5:1, büyük başlık ≥3:1).
