      summary: Anonymous ATS score (pre-auth lead magnet, paste text)
      description: Returns a top-line ATS compatibility score (0-100) plus the top 3 matching and missing keywords for an unauthenticated visitor. Uses ONLY free-tier OpenRouter models. Rate-limited 10/hour per IP. The full gap analysis, rewrite suggestions, and keyword strategy are intentionally NOT returned here - they remain behind the email-gate / signup wall.
