Goal
   Objectif est d'identifier l'origine d'une recette de cuisine et de retourner un code correspondant dans un format JSON structuré.

    1. Recherche d’un pays mentionné dans la recette et extraction de son code ISO 3166-1 alpha-2.
    2. Détermination de l’origine culinaire du pays si aucun pays n'est explicitement mentionné.
    3. Identification d’un continent si aucun pays ne peut être déterminé.
    4. Retour du code WWW si l’origine ne peut être définie.

    Return Format
    Renvoies un objet JSON structuré comme suit :
    json
    {
        "data": "<code>"
    }
    - Si un pays est mentionné, utilise son code ISO 3166-1 alpha-2 (ex. : FR pour la France).
    - Si aucun pays n'est trouvé, renvoie un code de continent parmi :
        WAF (Afrique)
        WAS (Asie)
        WEU (Europe)
        WNA (Amérique du Nord)
        WSA (Amérique du Sud)
        WOC (Océanie)
    - Si aucune information ne permet de déterminer une origine, renvoie WWW.

    Warnings
    - Respecte l’ordre de priorité : pays → continent → code WWW.
    - Le code ISO 3166-1 alpha-2 doit être exact et valide si un pays est identifié.
    - Le format du JSON doit être strictement respecté et bien formatté.
    - Ne fais aucune supposition infondée sur l’origine de la recette.

  "title": "Coffee & Walnut Cake",
  "description": "Coffee cake with walnuts is such a classic combination - I love the taste of coffee cake, but oddly don't drink coffee that much - I'm more of a hot chocolate girl. However, a hot chocolate with a slice of coffee and walnut cake on the side is perfect. I love the light coffee-flavoured sponge, with the crunch of the walnuts in the sponge and on the top of the cake. The coffee-flavoured buttercream is smooth, silky and heavenly in every bite!",

    "Dissolve the coffee in the boiling water and leave to cool.",
    "Beat the butter on its own for about 5 minutes until nice and smooth. Add the icing sugar in two batches, beating in fully after each batch. Add the cooled coffee and mix again until smooth.",
