I'm trying to create an app that modifies the cart's theme file in some way by using ScriptTags and Assets API. But I wonder whether the "sections/cart-template.liquid" asset is used in every store or not 🤔
I'm curious if you discovered any info about this. Thinking about the same question at the moment. Wondering if differing themes would lead to different files, and how much the structure of the file would change.
