Hi,
Not sure which PS version you are using but you might want to read this: https://devdocs.prestashop.com/1.7/themes/getting-started/asset-management/
Especially "Registering in themes" part.
Or you could just add links to your assets directly in your theme header.tpl file.
No need controller override here....
Thanks
