        <h2>How you get access</h2>
        <p>You have been invited to one or more projects by a project manager. You have received an email with a personal access link. The link looks something like this:</p>
        <code style="display:block;background:#f3f4f6;padding:10px 14px;border-radius:8px;font-size:.85rem;word-break:break-all;margin:.75rem 0">https://your-instance.com/ext/abc123…</code>
        <p>This link is <strong>for your use only</strong>. Do not share it with others. You do not need an account or password – the link is your access.</p>
    </div>

    <div class="help-ext-section">
        <h2>Your task overview</h2>
        <p>When you open the link, you will see all tasks assigned to you. Tasks are grouped by status (e.g. <em>Open, In Progress, Done</em>).</p>
        <p>Each task card shows:</p>
        <ul>
            <li>Task title</li>
            <li>Priority (Low / Medium / High / Urgent)</li>
            <li>Due date (if set)</li>
        </ul>
        <p>Click a card to open the detail view.</p>
    </div>

    <div class="help-ext-section">
        <h2>Update a task's status</h2>
        <p>You can change a task's status yourself to report progress:</p>
        <ol>
            <li>Open the task by clicking the card.</li>
            <li>Select the new status from the <strong>Change status</strong> dropdown.</li>
            <li>The change is saved immediately and is visible to the project manager.</li>
        </ol>
        <p>Alternatively you can drag the card to another column on the Kanban board via <strong>drag &amp; drop</strong>.</p>
    </div>

    <div class="help-ext-section">
        <h2>Write comments</h2>
        <p>In the task detail view you will find the comment section at the bottom. Here is how to comment:</p>
        <ol>
            <li>Enter your name in the <strong>Your name</strong> field.</li>
            <li>Write your comment in the text field.</li>
            <li>Click <strong>Send comment</strong>.</li>
        </ol>
        <p>Comments are visible to all project members and help keep the communication history traceable.</p>

    <div class="help-ext-section">
