<h3>Developer Notes</h3>
<h4>Registering Custom Block Variations</h4>
You can register custom carousel variations using <code>wp.blocks.registerBlockVariation()</code> and pass Splide configuration options via the <code>splideOptions</code> attribute.
Example: Carousel with Grid Fallback at Tablet
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
 name: 'carousel-to-tablet',
 title: 'Carousel / Grid Tablet',
 attributes: {
 template: 'default',
 splideOptions: {
 type: 'loop',
 perPage: 1,
 arrows: true,
 pagination: true
 },
 breakpoints: {
 tablet: {
 layout: {
 type: 'grid',
 columnCount: 3
 }
 }
 }
 },
 scope: ['block', 'inserter', 'transform']
});
</code></pre>
Example: Auto-Width Carousel
<pre><code>wp.blocks.registerBlockVariation('groundworx/carousel', {
 name: 'auto-width-carousel',
 title: 'Auto Width Carousel',
 attributes: {
 splideOptions: {
 type: 'loop',
 fixedWidth: '300px',
 focus: 'center',
 gap: '1rem'
 }
 }
});
</code></pre>
<h4>Adding Custom Templates</h4>
Use the <code>groundworx.carousel.templates</code> filter to add custom templates:
<pre><code>wp.hooks.addFilter(
 'groundworx.carousel.templates',
 'my-theme/add-custom-template',
 (templates) => [
 ...templates,
 {
 label: 'My Custom Template',
 value: 'my-custom'
 }
 ]
);
</code></pre>
Then add your template styles in your theme:
<pre><code>.template-my-custom .splide__slide {
 /* Your custom styles */
}
</code></pre>
<h4>Supported Breakpoints</h4>
The carousel supports 7 configurable responsive breakpoints plus a mobile/default base, following a mobile-first approach:
<ul>
<li>Mobile/Default: 0-374px (base configuration)</li>
<li>phone: 375px and up</li>
<li>large-phone: 480px and up</li>
<li>tablet: 680px and up</li>
<li>large-tablet: 960px and up</li>
<li>laptop: 1080px and up</li>
<li>desktop: 1280px and up</li>
<li>large-desktop: 1440px and up</li>
</ul>
Settings cascade from mobile to larger screens. Override at any breakpoint to change behavior.
Grid Fallback Breakpoints: 
For grid fallback functionality, you can use any of the 7 breakpoints: <code>phone</code>, <code>large-phone</code>, <code>tablet</code>, <code>large-tablet</code>, <code>laptop</code>, <code>desktop</code>, or <code>large-desktop</code>.
<h4>Splide.js Options</h4>

<ul>
<li><code>type</code>: ‘slide’, ‘loop’, or ‘fade’</li>
