Does Replo inject code in my Shopify theme upon installation

I have a client who is concerned with Replo injecting code upon installation on the site that will interfere with their theme, is there a short answer I can share back with him alleviating his fear?

We’ve got an FAQ section about adding unnecessary javascript here:

One other thing to note is that when you publish pages, Replo actually will add content to the theme, since it needs to in order to publish the page - we have some docs on how this relates to switching themes etc here

We priritize protecting your page speed, and 100% do not load unused code, we only load our code on pages that contain Replo content.
