   Apollo Militares | folha de estilo unica das 4 paginas de venda
   index.html (visao geral) | aqa.html | ama.html | banco.html

   ESTETICA: uma unica pagina escura, de ponta a ponta, igual a plataforma
   do aluno (front-end/src/index.css). Nada de secao branca no meio.

   Tokens (mesmos valores do modo escuro da plataforma):
     fundo      hsl(222 47% 8%)  = #0A1122
     painel     hsl(222 47% 10%) = #0F1A2E
     texto      hsl(210 25% 95%) = #E8EEF7
     verde      hsl(160 84% 45%) = #12C794   (accent / sucesso)
     azul       hsl(214 100% 55%) = #2E90FF  (primary)
     ambar      hsl(38 92% 50%)  = #F5B23B   (warning)
     roxo       #8B5CF6                      (foguete do logo)
