Is Boostrap CSS file used in Debut theme?

[mfcss]

I'm getting a warning from Google PageSpeed regarding the follow Bootstrap CSS file:

https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

It is unclear what this is used for in the Debut theme, yet at the same time it is also difficult for me to determine how to remove it - and whether it'll break something. Anybody has any idea on how to do this? From what I can see, it is part of a trekkie script.

By default Debut theme doesn't use Bootstrap, if someone did add that manually to the theme files.

It should be another app installed on your Shopify store that inject this code.
