Very nice. For those of us who'd appreciate a live demo (like me), I wrote this script:<p><pre><code> document.querySelectorAll('link[rel="stylesheet"], style').forEach((style) => style.remove());
const style = document.createElement("style");
style.appendChild(document.createTextNode("body{font-family:sans-serif;line-height:140%;max-width:38rem;padding:2rem;margin:auto}h1,h2,h3,h4,h5{margin-bottom:.6rem;line-height:120%}p{margin:0 0 1rem}"));
document.head.appendChild(style);</code></pre>
