3//! Spatial engine primitives shared by Origin, Lite, and WASM: R*-tree with
4//! bulk load and nearest-neighbor / range queries, geohash and H3 hex
5//! indexes, OGC predicates (ST_Contains, ST_Intersects, ST_Within,
6//! ST_DWithin, ST_Distance, etc.), WKB / WKT / GeoJSON interchange, and
7//! hybrid spatial-vector composition.
8//!
9//! Spatial collections are picked per-collection via `WITH (engine='spatial')`
10//! and use the columnar storage core; this crate provides the index
11//! structures and predicate evaluators only.
