/*
 * Vitrine da página inicial (as 3 homes: /, /pt/, /es/).
 *
 * Carregado só nelas, para não pesar nas outras 90 páginas.
 *
 * Duas regras de desempenho: só anima `transform` e `opacity` (rodam na GPU,
 * sem recalcular layout) e tudo o que se move para quando o aparelho pede
 * movimento reduzido. O CSS-base de cada cena é o estado FINAL; os keyframes
 * só descrevem de onde ela parte. Assim, sem animação, a cena aparece pronta.
