+// --- "passport stamps" reverse geocoding -----------------------------------
+// Reverse-geocodes a lat/lng pair into a { city, country } pair using the
+// Google Maps Geocoding API (REST), reusing the same PUBLIC_MAPS_KEY the
+// Maps JavaScript API loader already uses (see MapView.svelte) - the
+// Geocoding API must be enabled for this key in the Google Cloud Console for
+// this to work.
+//
+// Walks the first result's address_components looking for the 'locality'
+// type for the city name (falling back to 'administrative_area_level_1',
+// e.g. a state/province, for rural areas with no locality) and the 'country'
+// type for the country name. Returns { city: 'Unknown', country: 'Unknown' }
+// if the request fails or no results come back, so a failed lookup never
+// blocks stamp creation - it just produces a generically-labeled stamp.
