   TRANSIÇÃO DE PÁGINA (Swup) — fade + leve subida

   O Swup troca só o conteúdo de #swup (o <main>); header e footer
   ficam fora e permanecem fixos. Durante a troca o <html> ganha
   .is-animating: o conteúdo some descendo de leve e o novo entra
   subindo. Para trocar de transição, mexa só neste bloco.
