/* ============================================================================
   EDUON tasarim sistemi — kaynak: EDUON-AI-LMS-B2B-Responsive-Tasarim-Kodu
   (app/globals.css) uyarlamasi.

   UYARLAMA NOTLARI:
   - Tailwind import'u kaldirildi (tasarimin kendisi Tailwind sinifi
     kullanmiyor; yalnizca reset icin duruyordu). Kucuk reset eklendi.
   - Kenar cubugu iki kademeli: >1180px tam genislik, <=1180px cekmece.
     Orijinaldeki 82px ikon rayi BILINCLI atlandi: bu portalin menusu
     acilir-kapanir gruplu; ray geniligi grup listesiyle uyusmuyor.
   - Mevcut gorunumler Bootstrap 5 ile yazili; en alttaki "Bootstrap
     uyum katmani" btn/card/table/badge gorunumunu EDUON diline ceker,
     boylece ic sayfalar yeniden yazilmadan yeni dile oturur.
