   ------------------------------------------------------------
   - Este arquivo mantém o LAYOUT / ESTRUTURA do app (sidebar,
     tabs, canvas, containers, etc.)
   - Componentes reutilizáveis (botões, inputs, sliders, cards)
     ficam em: components.css
   - A intenção aqui é facilitar manutenção SEM mudar visual.
