   TheWhiteRussian · Kompozisyon — portal tasarım sistemi (2026-10-07)

   - Zemin beyaz ve ferah; yüzeyler gölgesiz, yalnız ince çizgiyle ayrılır.
   - Mürekkep: Rus okulunun mavi tükenmez kalemi — portalın tek vurgu rengi
     (bağlantı, birincil eylem, odak halkası).
   - Öğretmen kalemi: kırmızı. YALNIZ düzeltme, hata ve kapanmış süre içindir.
   - Yazı: arayüz ve başlıklar sistem sans'ı; serif (PT Serif) yalnız KÂĞITTA —
     kompozisyon yaprağı, öğrenci metni, oyun kelimeleri (`[lang="ru"]`).
   - İmza: çizgili defter yaprağı, sağda kırmızı pay; öğretmen notu oraya yazılır.
   - Tek tema: gündüz. İşletim sisteminin koyu tercihi İZLENMEZ (kullanıcı kararı).
