<h1>Mistwarp SB3 PostMessage Test</h1>
<div class="info">
<h3>How to use this feature:</h3>
<p>This page demonstrates how external applications can send SB3 files to Mistwarp using postMessage.</p>
<p>The message format should be:</p>
<div class="code">
{<br>
type: 'LOAD_SB3',<br>
data: ArrayBuffer | string (URL) | Uint8Array,<br>
title?: string<br>
}
</div>
</div>
<h3>Test Methods:</h3>
<div class="input-group">
<label for="urlInput">Load SB3 from URL:</label>
<input type="text" id="urlInput" placeholder="https://example.com/project.sb3" value="">
<input type="text" id="titleInput" placeholder="Project Title (optional)" value="">
<button class="button" onclick="loadFromUrl()">Load from URL</button>
</div>
<div class="input-group">
<label for="fileInput">Load SB3 from File:</label>
<input type="file" id="fileInput" accept=".sb3,.sb2,.sb" onchange="handleFileSelect(event)">
<button class="button" onclick="loadFromFile()">Load Selected File</button>
</div>
<div class="input-group">
<button class="button" onclick="loadSampleProject()">Load Sample Project (Cat Flying)</button>
</div>
<div class="iframe-container">
<iframe id="mistwarpFrame" src="http://localhost:8601/" title="Mistwarp Editor"></iframe>
