Path to production
The layered architecture (routes → controllers → services → data store) isolates the storage mechanism behind a single seam. Swapping the JSON store for a PostGIS repository, adding GeoServer tile/WMS layers, authentication, satellite imagery, and multi-user collaboration requires no changes to the presentation layer.
