        <p><strong>IsingForge Engine</strong> requires WebGPU to run high-performance stochastic simulations.</p>

        <p style="margin: 25px 0 8px 0;">How to fix it:</p>

        <p><strong>Chrome, Edge or Opera:</strong> Start the browser with the following flag:</p>
        <div class="flag">--enable-unsafe-webgpu</div>

        <p style="margin-top: 30px; font-size: 0.95rem; color: #aaaaaa;">
            Recommended: Use the latest <strong>Google Chrome</strong> or <strong>Microsoft Edge</strong>.<br>
            Firefox support is experimental and limited on Linux.
