Accessibility - Knots Not Clickable #172

Your current HTML for selecting a Knot is not accessible:

<div class="flex items-center">
   <input type="radio" name="domain" value="knot1.tangled.sh" class="mr-2" id="domain-knot1.tangled.sh">
   <span class="dark:text-white">knot1.tangled.sh</span>
</div>

This should use a label element, rather than a span.
