The package consistently throws 'L.GridLayer.GoogleMutant is not a constructor'
due to L-instance conflicts in the webpack bundle, despite multiple workaround
attempts. Removed package, transpilePackages entry, type stub, env var, and all
related component code. Traffic overlay dropped; geocoding (backend) unaffected.
Add leaflet-google-mutant@0.16.0 (exact/locked version) as a proper bridge
between the Google Maps JavaScript API and Leaflet. The old mt{s}.google.com
tile URL approach was unofficial and produced empty tiles.
Traffic layer now renders via createLayerComponent + googleMutant, loaded only
after the Maps JS API script is injected and ready (keyed off NEXT_PUBLIC_GOOGLE_MAPS_API_KEY).
Added leaflet-google-mutant to transpilePackages in next.config.mjs.
