{# Reusable "why isn't this enriched?" explainer. Self-contained — needs no
   template context. Used by the enrichment button and by the per-section

    Every bill carries a core record (title, sponsor, latest action) that
    Concord fetches up front. The detailed sections — cosponsors, action
    history, subjects, titles, and summaries — live behind separate
    Congress.gov endpoints, so they're fetched on demand rather than for all
    50,000+ bills at once. Until a bill has been enriched, those sections stay
    empty.
