        The engine ships a UMD bundle at
        <code>browser/jsColorEngineWeb.js</code>. Build it once, then
        start the dev server:
    </p>
    <pre><code>npm run browser   # build the UMD bundle
npm run serve     # start dev server on :8080 (samples + bench)</code></pre>
    <p class="lead" style="margin-top:12px">
        Then open
        <a href="http://localhost:8080/samples/">the landing page</a>
        or <a href="http://localhost:8080/samples/samples.html">/samples/samples.html</a> for the demo index. The bench is at

    <h2>ICCImage helper</h2>
    <p class="lead">
        All demos share a small immutable image wrapper:
        <a href="iccimage.js"><code>iccimage.js</code></a>.
        It handles the &ldquo;load image &rarr; transform &rarr; display&rdquo;
        plumbing so each demo stays under ~100 lines.
