/*
  about.css — "Quem é Priscila Santos" (#about).
  1) Apresentação: manifesto em linhas, colagem de fotos com selo girando e credenciais.
  2) Linha do tempo horizontal: a faixa fica presa na tela (position: sticky) e anda para o
     lado conforme a página rola (js/timeline.js). Sem GSAP, ou com "reduzir movimento",
     vira um carrossel nativo de arrastar (scroll-snap).
  Substitui os blocos de trajetória/credenciais que ficavam em styles.css e sections.css.
