/* O nome do usuário pode sumir, se for preciso — nunca os links.

   Faixa estreita do grid `1fr auto 1fr`: a coluna central é `auto`, então ela
   cresce com o conteúdo e as laterais encolhem até zero. Quando o conteúdo
   central passa da largura da lateral, ele transborda e a página ganha
   scroll horizontal.

   Medido no Chrome em 2026-09-27, com a barra logada em 5 links (Home, Sobre,
   Dashboard, Compras, Agenda), nome de 32px e botão "Sair" de 118px: precisa
   de 700px de conteúdo, e sobra folga a partir de 768px. Ou seja, o nome não
   precisa mais sumir em lugar nenhum da faixa de desktop.

   O breakpoint antigo (768-860px) existia quando a barra tinha menos links e
   o nome ocupava mais. Caiu por medição, não por suposição. Se voltar a
   faltar espaço, meça antes de esconder algo: esconder o nome do usuário é
   o último recurso, não o primeiro. */
