/* ==========================================================
   DRIVE GALLERY — Edições passadas (v1.42.0)

   Estrutura:
   1. Layouts da seção edições (grid | carousel | timeline | masonry)
   2. Galeria inline expansível (grid de fotos com lazy load)
   3. Lightbox custom (full screen, swipe, nav)

   Performance:
   - Lazy load via IntersectionObserver (JS)
   - Animações com transform/opacity (GPU)
   - Skeleton loading
