/** This script adds the current breakpoint-name (as specified in the 'breakpoints' const)

 * Default breakpoint names and cutoff pixel values taken from Bootstrap 5's default responsive breakpoints:

 * Usage:
 * - include the script into your page and the class is updated, and will continue to update whenever

 * - optionally listen for the event via:
