/* =====================================================================================
   Alkin Korkut - Portfolyo (statik surum) stilleri
   =====================================================================================
   Non-teknik not: Ana projedeki Next.js sitesi Tailwind ile yazilmisti. Burada Tailwind yok; ayni gorunum
   elle yazilmis CSS ile veriliyor. Renk, olcu ve gecis degerleri Tailwind'in varsayilanlarindan birebir
   alindi (yorumlarda karsilik gelen Tailwind sinifi yaziyor), boylece iki site ayni gorunur.

   Teknik notlar:
   - Koyu tema: <html class="dark"> varken ".dark ..." kurallari devreye girer (Tailwind'in darkMode: "class"
     ayariyla ayni mantik). Sinifi index.html'deki kucuk script ve main.js koyup kaldiriyor.
   - Kirilma noktalari Tailwind ile ayni: sm = 640px, lg = 1024px.
   - Kullanilan Tailwind renkleri:
       zinc   50 #fafafa | 300 #d4d4d8 | 400 #a1a1aa | 500 #71717a | 600 #52525b | 700 #3f3f46
              800 #27272a | 900 #18181b | 950 #09090b       (zinc-900 = rgb(24 24 27), zinc-950 = rgb(9 9 11))
       violet 300 #c4b5fd | 400 #a78bfa | 500 #8b5cf6 | 600 #7c3aed
       indigo 400 #818cf8 | 500 #6366f1      emerald 400 #34d399
