   article.css — richer editorial layout for blog article pages.
   Layered on top of styles.css. Used by post.html (dynamic Supabase
   posts) and blog-post.html (static). Adds:
     · breadcrumb
     · cover-image banner overlapping the hero
     · two-column layout with a sticky table of contents
     · social share buttons (horizontal in hero, vertical in sidebar)
     · pull-quote / callout styling
