  <h1>NimbusPay Support Knowledge Base</h1>
  <p class="meta">Customer support docs · Powered by Document Q&A</p>

  <p>
    Welcome to NimbusPay's support knowledge base. Use the chat bubble in the
    bottom-right corner to ask questions about billing, pricing plans, security
    certifications, compliance requirements, and supported payment methods.
  </p>

  <div class="card">
    <strong>How it works:</strong> Every answer is grounded in NimbusPay's
    official documentation. The widget shows you exactly which passages were
    cited, so you can verify the source before acting on the answer.
  </div>

  <h2>
    Ingested documents
    <button class="btn-refresh" id="refresh-docs" title="Refresh document list">↻ Refresh</button>
  </h2>
  <div id="doc-list">
    <p style="color:#999; font-style:italic;">Loading…</p>
  </div>

  <h2>Sample questions to try</h2>
  <p>
    Click the <strong>💬</strong> bubble → type one of these:
  </p>
  <ul style="margin:0 0 16px 20px; line-height:2;">
    <li>How much does the Growth plan cost?</li>
    <li>Is NimbusPay SOC 2 certified?</li>
    <li>What payment methods are supported?</li>
    <li>What's the weather today? <em>(expect a grounded refusal)</em></li>
  </ul>

  <p style="color:#555; font-size:0.9rem;">
    The chat widget is isolated from this page's styles via Shadow DOM — the
    aggressive global CSS above (crimson buttons, dashed div borders, etc.) does
    not affect the widget's appearance.
  </p>
