+// Q: Why is this not in @types?
+// A: `@types` is for types that are part of the public API. This is just a bunch of utilities we use throughout the codebase. (Mostly by Erika)
+
+// Merge all the intersection of a type into one type. This is useful for making tooltips better in the editor for complex types
+// Ex: The Image component props are a merge of all the properties that can be on an `img` tag and our props, in the editor
+// this results in a very opaque type that just says `ImgAttributes & ImageComponentProps`. With this, all the props shows.
