Adds a web app manifest, Workbox service worker (via vite-plugin-pwa),
and placeholder icons so the app can be installed to a home screen /
app window. App shell is precached for offline load; API and upload
requests stay network-only so city data and photos are never served
stale. Desktop browser access is unaffected.

React/Vite frontend and Express/SQLite backend for tracking visited and
planned cities on a map, with per-city notes, photos, links, and
participant-based sharing between family members. Includes session auth
with admin-managed user accounts, an OSM/Nominatim geocoding proxy, and a
single-image Docker deployment.
