/*
  biodata.css — estilos compartilhados (home, /blog e posts)

  Linguagem visual: o tema padrão do ggplot2.
  Painel cinza, grade branca, a linha azul do geom_smooth,
  faixas de facet como rótulos, saída do R como objeto de leitura.

  Organização:
    1. tokens e base
    2. topo, botões, rodapé
    3. peças da home reaproveitadas (rcode, facets, console anotado, faq)
    4. /blog (listagem)
    5. post (artigo)

  Compatível com o HTML que o Quarto gera: os estilos do artigo valem para
  elementos simples dentro de .post-body (h2, p, table, pre, figure),
  e o bloco ::: {.cta} do Quarto vira <div class="cta">, já estilizado.
