  Chatmail — site stil dosyası (assets/css/style.css)
  index.html (ana sayfa) ve giris.php / kayit.php (giriş, kayıt) tarafından ortak kullanılır.
  Yapı:
    1. Tasarım değişkenleri (:root) — renkler, yazı tipleri, hareket (easing/süre)
    2. Sıfırlama, temel öğeler, klavye odak halkası
    3. Yardımcı sınıflar (.container, .btn, .pill ...)
    4. Üst menü (.site-header; mobilde yumuşak açılan panel, hamburger → X)
    5. Hero + kampanya oluşturucu mockup (.hero, .mock, .toast)
    6. Bölümler: kanallar, özellikler, adımlar, senaryolar, KVKK bandı
    7. Fiyatlandırma (.plans, .billing-toggle, .rate-table, .addons)
    8. SSS (<details>; JS varsa yükseklik animasyonlu)
    9. CTA bandı ve footer
   10. Giriş sayfası (.auth, form öğeleri)
   11. Hareket: giriş sekansı, kaydırınca belirme (.reveal), hover/active, reduced-motion
   12. Mobil kırılımlar (@media)
  Hareket dili: tek easing (--ease), 0,5–0,7 s süreler, yalnızca transform/opacity; sürekli dönen dekor yok.
  Yazı tipleri Google Fonts'tan: Bricolage Grotesque (başlık), Manrope (metin).
