   2026-08-29 Rossum dilbilgisi ("açık sayfa, iki koyu bant") ile doğdu;
   09-01'de (Serdar) eski AÇIK-ZEMİNLİ BÖLÜMLER KALDIRILDI — sayfa koyudur;
   tek beyaz bölüm ICP akordeonu (#icp, r.3 — sections.css). Bu dosyada
   kalanlar: token'lar, taban, chrome (header/footer),
   hero, tez şeridi, kapanış. Tahta stili story2.css'te; yeni bölümler
   (#caps, #icp) sections.css'te. Açık-zemin token'ları (--s-*, --ink…)
   SİLİNMEDİ: ICP sahnelerindeki beyaz ürün pencereleri kullanır.
