   Âncoras x header fixo (corrigido 2026-08-21)
   O .site-header é `position: sticky; top:0` com 76px + 1px de borda. Sem isto o
   navegador rola até o topo EXATO da seção, o header cobre essa faixa e o que fica
   visível logo abaixo dele é o fim da seção anterior — o efeito de "vazar pedaço"
   da seção errada ao clicar em "Quem somos".
   `scroll-padding-top` no elemento raiz é a forma recomendada: vale para clique em
   link, navegação por teclado e :target, sem precisar tocar em cada seção.
