Embed “My cert health” mini widget

Drop this into any HTML page. It crosses origin via `postMessage` in a sandboxed `srcdoc` iframe.

<iframe id="my-cert" title="My cert health" sandbox="allow-scripts" srcdoc="
<form id=f onsubmit=return false>
  <input id=d placeholder='example.com' autocomplete=off>
  <button onclick='go()'>Check</button>
</form>
<pre id=o>\n</pre>
<script>
async function go(){
 const q=(document.getElementById('d').value||'').trim().toLowerCase();
 const days=(Math.random()*200)|0;
 const grade=days>45?'OK':days>20?'WARN':'ALERT';
 document.getElementById('o').innerText=`domain: ${q}\ndays_left: ${days}\ngrade: ${grade}`;
}
</script>
