// 1️⃣ Sélection des widgets
// -------------------------------
const climat = document.querySelector('.widget.climat');
const securite = document.querySelector('.widget.securite');
const energie = document.querySelector('.widget.energie');
const lumiere = document.querySelector('.widget.lumiere');
const alertes = document.querySelector('.widget.alertes');

// -------------------------------
// 2️⃣ Hover dynamique sur les widgets
// -------------------------------
function setupHover(widget, colorNormal, colorHover) {
    widget.addEventListener('mouseenter', () => {
        widget.style.backgroundColor = colorHover;
    });
    widget.addEventListener('mouseleave', () => {
        widget.style.backgroundColor = colorNormal;

setupHover(securite, '#D3D3D3', '#C0C0C0');
setupHover(energie, '#FFFACD', '#FAFAD2');
setupHover(lumiere, '#F5F5DC', '#FFF8DC');

// -------------------------------
// 3️⃣ Simulation d'alerte visuelle
// -------------------------------
function showAlert(widget) {
    widget.classList.add('alert');
}

// Exemple : activer l'alerte sur climat
showAlert(climat);

// Le bloc alertes reste visible
alertes.style.display = 'block';
