+        <p>The interactive setup wizard handles everything:</p>
+        <ul>
+          <li>Pre-flight checks (Docker, ports, RAM)</li>
+          <li>Database password configuration</li>
+          <li>Cryptographic key generation (JWT, credential encryption)</li>
+          <li>Admin account creation</li>
+          <li>SMTP configuration (optional)</li>
+          <li>Domain and reverse proxy setup (Caddy, nginx, Apache, HAProxy, Traefik)</li>
+          <li>OpenBao (KMS) bootstrap with automatic credential capture</li>
+          <li>Docker image builds (sequential to avoid OOM)</li>
+          <li>Stack startup and health checks</li>
+        </ul>
+        <p>No manual <code>.env</code> editing required. The wizard generates <code>.env.prod</code> with production-strength secrets and starts the full stack.</p>
