FastAPI service backed by PostgreSQL+PostGIS: cities/places/place_content schema (normalized per-language, per-length content for easy future re-ingestion), Alembic migration, an iterative-radius-expansion nearby search endpoint, a name-search fallback for denied-location flows, and a YAML seed loader CLI. Verified end-to-end against a live Docker Postgres+PostGIS instance (migration, city seed, place/content CRUD, and nearby radius expansion all confirmed working via curl).
