      <h1>⚠️ Configuration Error</h1>
      <p>
        It looks like you're using <code>Poke</code>'s own Invidious API endpoint
        (<code>${officialApi}</code>) for your custom instance.
      </p>

      <p>
        Please edit your <code>config.json</code> to match your own setup — using
        Poke’s shared API is kinda lame 😅 since it also rate-limits <b>poketube.fun</b>
        itself when too many people use it.
      </p>

      <p>
        Set up your own Invidious instance instead — it’s easy!  
        See the official setup guide:  
        <a href="https://docs.invidious.io" target="_blank">docs.invidious.io</a>
      </p>

      <p style="margin-top: 1em; color: #999;">
        Once you've updated <code>config.json</code>, restart your server and everything will work fine. 
      </p>
