/* =========================================================
   FUTTURE.ai — Home (index.html) · camada de redesign enterprise
   Carregado SO pelo index.html, depois do style.css e do site.css.
   Tokens, tipografia, botoes, header, FAQ e footer moram no site.css
   (compartilhado com as outras paginas); aqui ficam so as secoes da home.

   Direcao (guia "Prompting for frontend aesthetics", claude-cookbooks):
   - Tipografia: IBM Plex Sans no lugar de Inter/Sora. Familia tecnica,
     de engenharia; contraste por peso (300 no texto de apoio, 600 nos
     titulos) em vez de trocar de fonte.
   - Cor: o navy do hero (#04102C) vira a cor estrutural da pagina e o
     laranja da marca fica reservado para acao (CTA) e para o fim da
     cadeia de inteligencia. Sem gradiente decorativo.
   - Layout: alinhado a esquerda, cabecalho em coluna lateral, grades
     com divisorias finas (como uma matriz de controles) em vez de
     cartoes com sombra.
   - Movimento: so dois momentos — a entrada do hero (CSS) e a cadeia
     acendendo etapa por etapa quando entra na tela.
