/* Widget embarqué dans le panneau latéral droit de previsionnel.ch.
 *
 * Contrainte de départ : le panneau fait 380px de large et toute la hauteur
 * utile (`calc(100vh - 3.5rem)`), et il est redimensionnable par l'utilisateur.
 * Tout est donc fluide, et rien ne suppose une largeur confortable.
 *
 * Les tokens reprennent ceux des pages démo pour rester dans la charte Fondetec.
