/* ==========================================================================
   Hero (banner + H1/subtítulo/CTA)
   A imagem usa aspect-ratio igual à proporção real do arquivo (1600x560),
   então background-size: cover nunca precisa cortar nada — o banner
   aparece sempre inteiro. Em telas estreitas não há altura suficiente
   para sobrepor texto, então o texto fica abaixo da imagem; a partir de
   860px (mesmo ponto em que o menu deixa de ser hambúrguer) o texto passa
   a ficar sobreposto à imagem, que continua inteira por baixo.
