/* ==========================================================================
   articles-front.css — token-skin for the Articles module front-end (ST9)
   --------------------------------------------------------------------------
   The Articles renderer (ArticlesRenderer.php) emits NEUTRAL, unstyled BEM
   classes (`.articles-grid`, `.article-card*`, `.articles-pagination*`) and
   the single-article view (blog-article.html / fallback) uses `.article-detail*`.
   This file re-skins them to the storefront's editorial look using ONLY the
   semantic `--shop-*` tokens — no hex, no raw px in spacing — so an accent
   theme-swap in the admin repaints the blog along with the rest of the site.

   Loaded as a standalone <link> AFTER storefront.css in the layout, so any
   (0,2,2) selector here wins ties against the base link-colour trap
   (`body.storefront a:not(.storefront-btn){color:inherit}`, storefront.css:27).
