   Estratégia de breakpoints:

     - tablet   : >= 768px  — mais largura e listas em 2 colunas quando fizer sentido.
     - desktop  : >= 1024px — layout "de verdade" (painel largo, formulário + croqui lado a lado nas
                  etapas de estrutura, etapas sempre em uma linha).
     - desktop grande : >= 1440px — limite de largura máxima para não esticar demais em monitores grandes.
