/**
 * Type checker for raw OpenAPI v3.0 JSON schemas.
 *
 * `OpenApiV3TypeChecker` provides type guard functions for
 * {@link OpenApiV3.IJsonSchema} (raw, unemended format). For typia's normalized
 * format, use {@link OpenApiTypeChecker} instead.
 *
 * Key differences from v3.1: v3.0 uses `nullable: true` property instead of
 * union types, and has no `const` or tuple support.
