/* ===== Empurra o conteúdo da página para baixo quando há alerta =====
   --sab-height é definida dinamicamente pelo JS com a altura REAL do banner
   (considerando quebras de linha em mensagens longas). 72px é fallback.

   NOTA IMPORTANTE: algumas páginas (dashboard.css, contatos.css, etc.)
   definem `body { height: 100vh; overflow: hidden }` para layout full-screen.
   Usamos `box-sizing: border-box` + padding-top para que o padding fique
   DENTRO dos 100vh do body (em vez de esticar além da viewport). Depois
   reduzimos a altura dos containers flex internos (.dashboard-container,
   etc.) para caber no content-box restante. */
