}).addTo(map);
✅
Service Worker Caching
Offline map tile caching for progressive web app functionality.
// gnome-trail-sw.js
self.addEventListener('fetch', (event) => {
if (event.request.url.includes('/tiles/')) {
event.respondWith(
caches.match(event.request)
.then(response => response || fetch(event.request))
);
}
});
