    <p>Config node — not in the flow palette, but all six Collabora nodes need one.</p>
    <p>Without this, none of them do anything.</p>

    <h4>Two backends</h4>
    <ul>
        <li><strong>Nextcloud</strong> (<code>nextcloudUrl</code>) — files via WebDAV + Office API (OCS richdocuments)</li>
        <li><strong>Collabora CODE</strong> (<code>collaboraUrl</code>) — conversion engine (<code>/cool/...</code>). Internal CODE runs <strong>HTTPS</strong> (self-signed, <code>ssl.enable=true</code>): <code>https://code:9980</code> (shared Docker network) or fallback <code>https://&lt;bridge-ip&gt;:9980</code>, e.g. <code>https://172.17.0.2:9980</code>, after <code>docker network connect bridge nextcloud-node-red</code>. Plain HTTP (<code>http://code:9980</code>) fails — CODE refuses it when SSL is enabled.</li>
    </ul>

    <p><strong>Auth:</strong> username + <em>app password</em>. Not your normal account password.</p>
    <p><code>collaboraPublicUrl</code> — what the browser sees for WOPI/editor links, e.g. <code>https://docs.domain.name</code> (CODE proxied via Nextcloud/reverse proxy). Internal HTTP URLs won't work in an iframe.</p>
    <p><code>verifyTls</code> — must stay <strong>unchecked (false)</strong>: internal CODE uses a self-signed cert, so TLS verification would fail. Only enable it if <code>collaboraUrl</code> points at an endpoint with a trusted certificate.</p>
    <p>Default output folder in bridge if you omit a destination: <code>/Dokument/OfficeOut/</code></p>
