/* Posição do menu (Parâmetros → Interface, 2026-08-27) — só faz sentido lado-a-lado no ambiente
   de trabalho (>860px): abaixo disso o menu do backoffice já empilha por cima do conteúdo
   (flex-direction:column, ver bloco @media max-width:860px acima) e a barra do POS já se esconde
   por completo (ver pos.php), por isso trocar a ordem não teria efeito visível nenhum aí — e
   dentro de um flex-direction:column, "order" reordenaria para cima/baixo, não para o lado. Classe
   partilhada de propósito entre a sidebar do backoffice e a barra de ícones do POS (ambas usam
   .shell-side como base).*/
