   - Yarı saydam beyaz "cam" yüzeyler, 22px kart / 14px kontrol köşesi
   - Birincil buton: #1D4ED8 → #0369A1 degrade + camgöbeği parıltı
   - Yazı tipleri: Poppins (metin), Exo 2 (başlık, buton)
   - Modül renkleri panel etiketleriyle aynı: yeşil (depo), turuncu (pazaryeri), mor…
   - Koyu bölümler panelin koyu temasını kullanır (#06080F).
   - Logodaki yapboz sarısı (#FFC344 / #FFD15B) marka vurgusudur: EntegreSmart AI,
