Tide widget builder

<iframe src="https://auth.test.logged.cloud/embed/tide/holyhead?theme=dark" width="100%" height="490" style="border:0;max-width:680px;" loading="lazy" title="Holyhead tide times"></iframe>
<script>window.addEventListener("message",function(e){if(!e.data||!e.data.fishLoggedTideHeight)return;document.querySelectorAll('iframe[src*="/embed/tide/"]').forEach(function(f){if(f.contentWindow===e.source)f.style.height=e.data.fishLoggedTideHeight+"px";});});</script>

Paste this wherever you want the tide chart. It is a plain iframe: no signup, no tracking pixels, no JavaScript to maintain. The widget updates itself.
