   A WordPress-style blog on the shared design system: a hero, a filterable
   post GRID with a sidebar of widgets (search, categories, recent, tags, CTA),
   and a single-post reading template (featured media, prose, myth callout,
   tags, share, author, related). Logical properties throughout (RTL-first).
