   Amaç: uzun süre okunan sayfada göz yorulmasın. Bu bölüm EN SONDA durur ve önceki bölümlerin parlak/hareketli kararlarını ezer:
     - palet: neon yeşil yerine mat nane / adaçayı; saf beyaz yerine kırık beyaz; saf siyah yerine kömür (WCAG AA kontrast korunur)
     - parlama yok: box-shadow ışıması, drop-shadow, text-shadow, LED, fareyi izleyen ışık ve 3B eğim kapalı (ana sayfa dahil)
     - hareket yok: giriş animasyonu, fareyi izleyen PCB arka planı (js/script.js), hero devre izi
     - tipografi: ~68 karakterlik satır, 1.9 satır aralığı, 17-17.5 px gövde, daha az vurgu rengi
   Kapsam: body.blog-page (pages/blog.html) ve body.blog-article (pages/blog/*.html). Üst bar ve menü de aynı değişkenleri kullanır.
