<content></content>
<!-- index.html -->
<module href="./module.html" locals='{"foo": "strong"}'>
  <p>Or so they say...</p>
</module>

Result

<p>The foo is strong in this one.</p>
<p>Or so they say...</p>

attributeAsLocals

All attributes on <module></module> will be added to locals

Example:

<!-- module.html -->
<div class="{{ class }}" id="{{ id }}" style="{{ style }}">
  <content></content>
</div>
<!-- index.html -->
<module 
  href="module.html" 
  class="text-center uppercase" 
  id="example"
  style="display: flex; gap: 2;"
