   Progressive enhancement do "reveal on scroll".
   REGRA: sem JS, o conteúdo é 100% visível — nada depende do main.js
   pra aparecer. Quando o main.js executa, ele adiciona .js no <html>
   ANTES do primeiro paint (script no <head>) e SÓ então os elementos
   .reveal começam invisíveis pra entrar com transição via IntersectionObserver.
