/* Usa `translate` (propriedade própria, separada de `transform`) em vez de mexer em
   `transform` aqui — os cards com hover (.feature-card, .compat-card) já têm sua própria
   `transition:` para levantar no hover, e essa declaração inteira "vence" a de `.reveal`
   em empate de especificidade (a shorthand `transition` não mescla entre regras, só uma
   ganha). Por isso o delay do stagger vai embutido num `var(--reveal-delay)` dentro do
   próprio valor de opacity/translate de cada card — assim funciona não importa qual regra
   de transition "vença", desde que ela inclua opacity/translate com esse var (ver
   .feature-card e .compat-card mais abaixo). */
