   Long-form cost model in the v2 design. Reuses article.css (art-p, art-h2,
   art-quote, art-table + its phone card layout, art-win) and adds the
   article-only blocks with the `ia-` prefix (hero meta, hero chart, stats,
   table highlights, captions, sources, end CTA).
   Colours: --v2-* tokens, or the page tokens below (defined for both themes).
