   TASARIM İLKELERİ (bilinçli kararlar — lütfen bozmayın)
     · Tema baştan sona KOYU. Sitede beyaz alan yoktur; zeminler açılış
       videosunun kendi renginden türetildi, geçiş kesintisiz olsun diye.
     · Marka yeşili YALNIZCA vurgu. Logodaki #056839 koyu zeminde kontrast
       veremediği için açılmış türevi (#35C57E) kullanılır.
     · Gölge yok, glow yok, gradyan yok. Derinlik saç teli çizgilerle kurulur.
     · Köşe yarıçapı en fazla 3px. Yuvarlak "pofuduk" kart yok.
     · Simgeler emoji değil; inc/icons.php içindeki 1.5px çizgi SVG'ler.
     · Başlıklar serif (Source Serif 4), gövde teknik sans (IBM Plex Sans),
       ölçüm/etiket/rakam ise mono (IBM Plex Mono) — mühendislik dosyası hissi.
