  See blog-card.html for the full direction-contract comment.

  --cm-blog-card-bg / --cm-blog-card-fg are set inline per card (not
  nth-child, unlike Proyectos) since the color comes from the article's
  pillar — see scripts/lib/blog-pillars.mjs. Every pair below is reused
  verbatim from that config, already verified >=4.5:1 WCAG AA.
