  message: `Invalid runtime expression: "${value}". Runtime expressions must:
  - Start with $ or contain expressions in curly braces {}
  - Use one of: $method, $url, $statusCode
  - Or follow pattern: $request|response.(header|query|path|body)
  - For body refs, include valid JSON pointer (e.g. #/user/id)
  - For headers, use valid header names without spaces
  Example valid expressions:
  - Pure: $method, $request.path.id, $response.body#/status
  - Embedded: "Hello {$request.body#/name}!", "Status: {$statusCode}"`
}));
