/* MFM Advisor Research — Linha 03, Analise de Cenarios. E tambem o blog.
   Mesma gramatica do v3 do mfmadvisor.com: navy e dourado, Newsreader no display,
   Inter no corpo, IBM Plex Mono nos rotulos, texto justificado com hifenizacao,
   sangria de ponta a ponta. Sem card generico, sem emoji, sem simbolo decorativo.

   A diferenca de proposito: o v3 e uma capa que convence em uma tela. Este aqui e
   um site de LEITURA — a medida da coluna de texto manda mais que o efeito. */
