/*
  Facing Impulse — folha de estilo única.
  O quê ......: sistema visual da marca em CSS puro (tokens + layout + componentes).
                Paleta e tipografia vêm do manual de identidade: #000C0A, #007D64,
                #F4F4F4, #4F5655 e a família Satoshi.
  Depende de .: ../fonts/satoshi-{400,500,700,900}.woff2 · ../img/*
  Usado por ..: ../../index.html (único consumidor)
  Ao mexer ...: --green é a cor de MARCA (fundos/preenchimentos). Para texto sobre
                fundo escuro usar --green-t (mais claro) — #007D64 sobre #000C0A dá
                3.8:1 e falha AA em texto pequeno.
