### Class Structure

- **Utility classes**: `abstract` class + `protected` constructor

- For some Python-specific terms like "pickle", "list", "dict" etc, we don't have to translate them.
- Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 請求
- response (HTTP): 回應
- path operation: 路徑操作
- path operation function: 路徑操作函式
