- * This type is not part of the original Zod library, it's been added in Zui to:
- * - Brand the type as a ZuiType and avoid conflicts with 'zod' types
- * - Simplify the type checks and inference for `infer`, `input`, and `output`
- *
- * The original `infer` type inference on ZodType takes a lot of compute because the TS compiler has to check all the methods and properties of the class.
- * The fact that we add __type__ here allows the TS compiler to shortcircuit the type inference when it's not present and prevents infinite circular inferences
