//! Integration tests for enum-like schema generation (manual construction).
//!
//! Note: `#[derive(JsonSchema)]` lives in `fastapi-macros`, which depends on this crate.
//! Keeping macro-derive tests here creates a dependency cycle. These tests validate
//! the underlying schema types and serialization behavior instead.
