/* Landing de youtax.com.br: captação de DF-e e apuração de CBS e IBS (caminho A, cinema e deck).
   Paleta e contraste de dfe-captacao-main/design-system/youtax/MASTER.md: verde e ciano são
   preenchimento ou acento sobre o azul-marinho; texto verde sobre claro é #047857.
   Sem estilo embutido: a CSP do Caddy só aceita esta folha. O movimento (js/movimento.mjs) só escreve
   variáveis e transform pelo CSSOM; sem a classe com-movimento a página é estática e completa. */
