The specific problem is this body rule:<p><pre><code>    font-size: 1.6vmin;
</code></pre>
Font is now scaled to viewport.<p>This is what happens when users attempt to zoom:<p><a href="https:&#x2F;&#x2F;gyazo.com&#x2F;613a5fac45611005130160414a7dc0aa" rel="nofollow">https:&#x2F;&#x2F;gyazo.com&#x2F;613a5fac45611005130160414a7dc0aa</a><p>(Mobile may or may not have this issue as zooming may not be tied to viewport size.)<p>Bad Webmonkey. No donut.
