   overA Capital, page: Artigo  (single blog post / reading view)
   The detail page behind every card on blog.html. One shared template
   (artigo.html) renders any post from a slug; this is its dress.
   A calm, TYPE-FIRST reading column: centered masthead -> brand rule ->
   left-aligned prose at a comfortable measure -> "continue lendo" (reuses
   the .cnt- card grid) -> espresso CTA. Same Newsreader/Barlow duet as
   the blog index, so the article reads as a sibling, not a foreign page.
   Page-scoped under .art- ; the shell (header/footer + site.js) is shared.
