        <h3>How to Read This Analyzer</h3>
        <p>
          The Schema Change Summary card shows what changed between v1 and v2. The dependency paths show
          how events flow from producers through pipelines into downstream consumers.
        </p>
        <p>
          Nodes are color-coded by impact. Click any node to see how v2 affects that service
          or pipeline and which fields need updates.
