        <p><strong>What this dashboard is:</strong> a release control panel for OTA web-asset updates.  
        Your app checks this server for the latest version in a channel and downloads the linked archive.</p>

        <p><strong>How release selection works:</strong> clients read <code>releases.json</code> and use only entries with
        <code>status = released</code>. Draft and revoked entries stay visible to admins but are ignored by clients.</p>

        <p><strong>What each action does:</strong></p>
        <ul>
          <li><strong>Confirm</strong> -> marks a version as <code>released</code> (eligible for client updates).</li>
          <li><strong>Revoke</strong> -> marks a version as <code>revoked</code> (clients stop using it).</li>
          <li><strong>Draft</strong> -> marks a version as <code>draft</code> (prepared but not live).</li>
          <li><strong>Delete</strong> -> removes the release entry (and with purge also deletes files).</li>
        </ul>

        <p><strong>Current server summary:</strong>
        total=${stats.total ?? 0}, released=${stats.released ?? 0}, draft=${stats.draft ?? 0}, revoked=${stats.revoked ?? 0},
        stable=${stats.stable ?? 0}, beta=${stats.beta ?? 0}.</p>
