FAQ

Does it infer enums?: Not yet. It focuses on structural types. You can convert strings to z.enum manually.
Can I name the type?: Yes—set a schema name and the inferred type uses a capitalized version.
Why optional any?: When enabled, null values become optional fields for easier handling of sparse data.
