   FILME DE ABERTURA — Saborosa de Salinas
   Mobile primeiro. Um palco fixo (position: sticky) dentro de uma seção alta;
   a rolagem dentro da seção move a linha do tempo de script.js.
   Regra de desempenho: a rolagem só anima transform, opacity, um clip-path
   (frente da garrafa) e um stroke-dashoffset (montanhas gravadas).
