/**
 * Web Component: Custom Toggle Switch
 *
 * How to use in Webflow:
 * 1. Add an "Embed" element inside Webflow.
 * 2. Paste the following HTML:
 *      <custom-toggle label="Enable feature"></custom-toggle>
 * 3. Modify the "label" attribute to change the toggle description.
 * 4. Listen for toggle state changes using:
 *      document.querySelector('custom-toggle').addEventListener('toggle-change', (e) => {
 *          console.log('Toggle state:', e.detail.checked);
 *      });
 */
