   Estrutura de seções:
   .section-img  → seção com imagem de fundo (hero, features)
   .section-text → seção só texto, fundo preto puro (banners)
   
   As transições são suaves porque:
   - Cada .section-img tem um overlay com degradê:
     preto puro → transparente → preto puro
   - As .section-text são preto puro
   - Resultado: tudo se funde naturalmente
