    -apple-system, BlinkMacSystemFont, &amp;#x2F;&amp;#x2F; San Francisco on macOS and iOS

    &amp;quot;Liberation Mono&amp;quot;,                &amp;#x2F;&amp;#x2F; Linux
    Menlo, Monaco, Consolas,          &amp;#x2F;&amp;#x2F; A few sensible system font choices
    monospace;                        &amp;#x2F;&amp;#x2F; The final fallback for rendering in monospace.
