/* Shared blog styles for traceopt.ai/blog.
   Single source of truth for every blog post + the listing page, so the
   chrome stays consistent and a fix lands once instead of per-post.
   Pair with the site-wide /styles.css (compiled Tailwind). Palette follows
   the TraceOpt design system (DESIGN.md): orange #FF8C00 / #D2691E on warm
   white #fffdfa, ink #111827 for the footer/CTA block only.
