/* ============================================================================
   AKGROUP YAPI — v3 "Katman"
   ----------------------------------------------------------------------------
   Layer 2 (semantic) yeniden tanımı + Layer 3 (component) stilleri.
   Primitive token'lar css/tokens.css içinde; bu dosya onları SADECE semantic
   katmanı kurarken okur. Bileşen kuralları yalnızca semantic token okur.

   TASARIM YÖNÜ
   ------------
   Logodaki iki üst üste chevron ("katman") tasarımın ana fikri:
   numaralı indeksler, kaydırılmış/örtüşen bloklar, chevron dokusu ve
   hero'da soldan sağa açılan katman (clip-path wipe) geçişi.

   BASELINE OVERRIDE'LARI (tokens.css'tekilere ek)
   -----------------------------------------------
   1) Radius register
      tokens.css: kart 8px (--radius-lg), kontrol 4px (--radius-sm)
      v3:         kart/medya 12px (--radius-xl), kontrol 6px (--radius-md)
      Kapsam:     yalnızca v3
      Gerekçe:    Baseline §5.4, 200–500px yükseklikteki öğeler için 12–16px
                  öngörüyor; v3'ün medya blokları 320–520px. 8px bu ölçekte
                  optik olarak kayboluyordu. Kontrol 6px, Baseline §5.1
                  varsayılanı ve 40–48px kontrol yüksekliğiyle uyumlu.

   2) Başlık yazı tipi
      Baseline: --font-display: "Inter Display"
      v3:       Archivo (variable, wdth 62–125)
      Kapsam:   yalnızca başlık/display tipografi
      Gerekçe:  genişletilmiş grotesk yapı/strüktür okuyor ve markanın geniş
                wordmark'ıyla (AKGROUP) aynı ritimde. Gövde metni Inter kalıyor.

   3) Hero geçiş süresi
      Baseline §8.3: tam ekran geçiş 400–480ms
      v3:            480ms (--duration-page) — sınırın içinde, override değil.
