En héritant de `str`, la documentation de l'API saura que les valeurs doivent être de type `string` et pourra donc s'afficher correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs valides disponibles :

* **Confusion for users and contributors**: Mixed spellings (e.g., "color" and "colour", "initialize" and "initialise") in the codebase create confusion about which variant to use
* **Harder code search and refactoring**: Searching for identifiers, method names, or documentation becomes more difficult when multiple spellings exist for the same concept
* **Inconsistent API surface**: Public APIs with mixed spelling conventions appear less professional and polished
