   ETAPA 9: HERO COM VIDEO, RESEARCH
   Um video por pagina. A home tem a orca, a Research tem a agua-viva.
   Nenhuma outra pagina recebe video.

   A altura do hero e definida pelo conteudo, nao pelo viewport. Isso faz
   a posicao vertical do texto, e portanto o contraste, nao variar com a
   altura da tela, ao contrario da home.

   Contraste medido em 15/10/2026, contra quadro 100% branco, que e o teto
   de luminancia possivel apos grayscale e contrast(1.1):
     375px  topo em 25.0%  ->  7.80:1
     768px  topo em 30.5%  ->  8.09:1
     1920px topo em 26.5%  ->  7.88:1
   Pior caso 7.80:1, dentro de AAA.
   Os tres pontos do gradiente sustentam essa conformidade: nao enfraquecer.
   Qualquer mudanca no padding ou no tamanho do texto exige recalcular.
