   STLYES.CSS — Gallardo E-Katalog — ANA SAYFA

   Üst şerit: marka + 3D logo + adres/telefon + web sitesi.
   Ana alan: her proje tam-yükseklik bir "cephe" (facade) paneli;
   masaüstünde üzerine gelince genişler (CSS :hover), dokunmatikte
   JS (mainpage.js → _wireDelegatedEvents) is-active sınıfını
   karşılığında ekler/kaldırır. Veri akışı (GetAllProjects /
   GetSubProjects / handleProjectClick) HİÇ değişmedi — bu dosya
   sadece görünümü değiştirir, #projectsSidebar ve
   #subProjectsPanel id'leri JS ile birebir aynı kaldı.
