 *  Organisation :

 *    - En-tête
 *    - KPIs
 *    - Contrôles (filtres, tri) & légende
 *    - Grille de cartes (lignes)
 *    - États : chargement / erreur / vide
 *
 *  Les couleurs pilotées par la donnée (couleur d'une ligne, remplissage d'une
 *  jauge, etc.) sont posées en style inline par index.js ; ici on ne gère que
