/* blog.css — the blog / changelog layer for imanna.ai. Loads AFTER styles.css + pages.css and reuses
   their tokens (--bg/--bg2/--card/--card2/--border/--txt/--muted/--c1/--c2/--grad/--grad2) and chrome
   (.page-nav, .page-hero, .page-sec, .page-prose, .btn, .foot-*). Adds ONLY what a post list and a
   long-form article body need that the marketing sections did not: a card list, article typography,
   the quotable "short version" block, and the changelog rail.

   No new visual language: a blog that looks like a different product reads as a different product. */
