  16     \Drupal calls should be avoided in classes, use dependency injection  
         instead                                                               

Also, the tests don't run.

The JS comes from the official Broadstreet docs: https://information.broadstreetads.com/using-broadstreets-v2-tags/

Will deal with the loader.js problem separately: 📌 Update loader.js once Broadstreet Ads update it Active
