   00. TIPOGRAFIA · arquivos hospedados no próprio projeto
   --------------------------------------------------------------------------
   Outfit e Manrope são fontes VARIÁVEIS: um único arquivo cobre todos os
   pesos, o que reduziu o peso das fontes de 199 KB para cerca de 82 KB.
   Ficam aqui dentro (e não em um arquivo separado) para economizar uma
   requisição no carregamento — o que pesa em conexão de celular.
   Para regenerar, veja "Fontes" no LEIA-ME.

   FONTES DE ESPERA COM AS MESMAS MEDIDAS
   Enquanto Outfit e Manrope carregam, o navegador mostra Arial. Sem ajuste,
   a troca faz o texto "pular" (o Google penaliza isso como CLS) e obriga uma
   repintura que atrasa a nota de velocidade.
   Os percentuais abaixo foram calculados a partir das métricas reais de cada
   arquivo: com eles, Arial ocupa exatamente o mesmo espaço, e a troca fica
   imperceptível.

   As revelações ao rolar são controladas por JavaScript (assets/js/main.js).
   O CSS aqui cuida apenas do estado inicial do topo, para que o conteúdo
   não "pisque" antes de a animação começar.
   ========================================================================== */

/* --------------------------------------------------------------------------
   ABERTURA DO TOPO · CSS puro, sem depender do JavaScript
   O texto do topo é o maior elemento da tela — é ele que o Google cronometra
   como LCP. Animar por CSS faz a pintura acontecer imediatamente, em vez de
   esperar o GSAP baixar e executar.

   Usamos "backwards" (e não "forwards"): durante o atraso o elemento fica no
   estado inicial e, ao terminar, volta ao estilo normal. Assim o GSAP consegue
   controlar a opacidade depois, no efeito de vídeo fixo.
