/* ---------- OVERRIDE CRÍTICO ----------
   Alguns arquivos de conteúdo definem body{display:flex} ou display:grid
   pra ter o layout próprio deles (sidebar+conteúdo lado a lado). Sem isso
   aqui, o body flex/grid do arquivo "puxa" nosso cabeçalho/breadcrumb/
   sidebar pra layout errado também. Forçamos o body a empilhar em coluna
   sempre, e cada arquivo mantém seu próprio layout interno dentro da
   .cmed-nav-main (onde ele já usava display:flex/grid nos PRÓPRIOS
   elementos internos, isso continua funcionando normalmente). */
