   Best Finance Calculator — Article pages (/guides/…)
   ---------------------------------------------------------
   Loaded ONLY by individual article pages. Every rule is scoped
   under .article-body, so no existing page can be affected and
   the site's design and structure stay exactly as they were.
   Colours, radii, spacing and fonts all reuse existing tokens —
   this file introduces no new design language, only the prose
   typography that long-form articles need.
