/* ============================================================
   JOURNAL — Field Notes: o índice do blog e a página de artigo.

   Mesmo vocabulário do resto do site: capítulos, pegada do logo,
   fio como divisor, display em serifa e corpo em sans. Consome só
   os tokens de styles-base.css — nenhuma cor, fonte ou raio literal.

   Duas telas vivem aqui:
     .journal-index  → a lista de notas (blog/index.html)
     .article        → uma nota aberta (blog/<slug>.html)
