        <div class="test-step">
            <span class="step-counter">1</span>
            <strong>Initial Preview:</strong> Open this file in the Observable preview panel

        <div class="test-step">
            <span class="step-counter">2</span>
            <strong>First Disposal:</strong> Close the preview panel using the X button

        <div class="test-step">
            <span class="step-counter">3</span>
            <strong>First Recovery:</strong> Reopen preview (Ctrl+Shift+P → "Observable Kit: Preview")

        <div class="test-step">
            <span class="step-counter">4</span>
            <strong>Rapid Cycling:</strong> Repeat close/open cycle 5-10 times rapidly
