/**
 * Carte Lovelace pour l'intégration CookCLI — liste navigable des recettes.
 *
 * Le détail d'une recette n'est plus géré par cette carte : un clic sur une
 * ligne navigue vers une vue générée par cookcli-recipe-strategy.js (voir ce
 * fichier), qui affiche étapes/ingrédients/minuteur via des cartes natives
 * et des cartes tierces (tabdeck-card, simple-timer-card).
 *
 * Consomme cookcli/recipes (path, name, time, servings, tags, image_url).
 *
 * Installation :
 * 1. Copie ce fichier dans config/www/cookcli-card.js
 * 2. Paramètres -> Tableaux de bord -> menu ⋮ -> Ressources -> Ajouter :
 *    URL "/local/cookcli-card.js", type "Module JavaScript"
 * 3. Ajoute une carte manuelle sur un tableau de bord :
 *    type: custom:cookcli-card
 *    title: Mes recettes
 *    detail_view_path: recette   # doit correspondre au "path" de la vue de détail
