/* seo-blog-engine enrichment blocks (1.10.1). Scoped to .sb-*; a site can override any rule.
   --sb-accent / --sb-light / --sb-text come from site.yaml enrich.palette (prepended above).
   Every box sets BOTH its background and its text colour: most of our sites are dark-themed, and
   a box that inherits the page's light text onto a light fill is unreadable (found 2026-10-05,
   before the first enriched article). No prefers-color-scheme rules for the same reason — the
   site's own theme, not the OS setting, decides the page colours. */
