SVG中Press Start 2P字体无法加载的问题求助

我需要将以下SVG渲染为独立文件：

<svg width="89" height="55" viewBox="0 0 89 55" fill="none" xmlns="http://www.w3.org/2000/svg">
    <style>
    @font-face {
        font-family: 'Press Start 2P';
        src: url('https://fonts.googleapis.com/css?family=Press+Start+2P');
    }
    </style>
    <rect width="89" height="55" fill="black" />
    <rect x="5.5" y="5.5" width="78" height="44" fill="#0000FF" />
    <text text-anchor="middle" x="44.5" y="31" fill=" white" font-family="Press Start 2P" font-size="12" letter-spacing="0em">1234</text>
    <rect x="78" y="45" width="9" height="8" fill="#FF4F0A" />
    <rect x="5.5" y="5.5" width="78" height="44" stroke="#FF4F0A" stroke-width="3" />
    <path d="M81.4286 51V50.4286H81V49.8571H81.8571V50.4286H83.1429V49.2857H81.4286V48.7143H81V47.5714H81.4286V47H83.5714V47.5714H84V48.1429H83.1429V47.5714H81.8571V48.7143H83.5714V49.2857H84V50.4286H83.5714V51H81.4286Z" fill="#0000FF" />
</svg>

我尝试使用Press Start 2P字体，但无论本地打开SVG文件，还是通过以下Data URI方式，字体都无法渲染：

根据建议，我尝试将完整字体以Base64编码嵌入SVG（编码内容来自.ttf文件转换），但问题依旧：

<svg width="89" height="55" viewBox="0 0 89 55" fill="none" xmlns="http://www.w3.org/2000/svg">
    <defs>
        <style>
        @font-face {
            font-family: "Press Start 2P";
            src: url(data:application/font-woff;charset=utf-8;base64,..) format("woff");
            font-weight:normal;font-style:normal;
        }
    </style>
    </defs>
    <rect width="89" height="55" fill="#E5E5E5" />
    <rect width="89" height="55" fill="#29296E" />
    <rect x="5.5" y="5.5" width="78" height="44" fill="#0000FF" />
    <text text-anchor="middle" x="44.5" y="31" fill=" white" font-family="Press Start 2P" font-size="12">
    {}azer
    </text>
    <rect x="5.5" y="5.5" width="78" height="44" stroke="#FF4F0A" stroke-width="3" />
    <rect x="47" y="45" width="41" height="8" fill="#FF4F0A" />
    <text text-anchor="end" x="86" y="52" fill=" white" font-family="Press Start 2P" font-size="8" letter-spacing="0em">

    </text>
