   styles_base.css — Reset, tipografia e header compartilhado
   Usado por: index.html e sobre.html

   NOTA overflow-x:
   Usamos "clip" (não "hidden") para evitar overflow horizontal.
   - "hidden" cria um scroll container → quebra position:sticky
   - "clip" corta visualmente SEM criar scroll container → sticky funciona
   O !important vence o body.style.overflow = 'auto' que o script.js
   aplica via inline style ao fechar o modal.
