jQuery 4.0 has removed the "$.type" method. As a result, slick can't properly identify that we have the "responsive" settings array. <img width="887" height="109" alt="Image" src="https://github.com/user-attachments/assets/80a608de-b1b6-48c9-a94e-7f5217a1b8f2" /> <img width="598" height="217" alt="Image" src="https://github.com/user-attachments/assets/adefb68c-40e7-4b47-8c1f-a7d5e02b5b90" /> This call should be replaced with native browser methods (Array.isArray in this case).
