/**
 * OpenAPI v3.1 specification types (raw, unemended).
 *
 * `OpenApiV3_1` contains TypeScript type definitions for raw OpenAPI v3.1
 * documents as-is from the specification. Unlike {@link OpenApi}, this preserves
 * the original structure including `$ref` references and `allOf` compositions
 * without normalization.
 *
 * Key features in v3.1:
 *
 * - JSON Schema draft 2020-12 compatibility
 * - `type` can be an array: `type: ["string", "null"]`
 * - `const` keyword for constant values
 * - `prefixItems` for tuple definitions
 * - Webhooks support
 *
 * For a normalized format that simplifies schema processing, use
 * {@link OpenApi}.
