        This example demonstrates how to integrate the Nevent Subscriptions SDK using a simple <code>&lt;script&gt;</code> tag.
        No build process, no npm, no bundler required - just copy and paste!

    <!-- Info Box -->
    <div class="info-box">
      <h3>🚀 Quick Start</h3>
      <p>
        This page loads the SDK from our CDN at <code>dev.neventapps.com/subs/latest/</code>.
        In production, always use versioned URLs like <code>neventapps.com/subs/v2.0.0/</code> to prevent breaking changes.
      </p>
      <p>
        <strong>Note:</strong> This is a demo with placeholder IDs. Replace <code>newsletterId</code> and <code>tenantId</code> with your actual values.
