  Estrutura visual: sidebar, header mobile, navegação inferior, área principal e responsividade estrutural.

  COMO EDITAR:
  - Altere variáveis de cor, espaçamento e sombras preferencialmente em 01-base.css.
  - Evite duplicar classes: procure primeiro se já existe um componente equivalente.
  - Comentários com 'AJUSTE AQUI' indicam pontos comuns de personalização.
