//! Vector search acceleration structures.
//!
//! Use these *in front of* exact cosine scoring to eliminate candidates
//! before doing expensive dot-product math.
//!
//! | Structure | Algorithm | Tradeoff |
//! |------------|-----------|-----------------------------------|
//! | [`LshIndex`] | LSH w/ random projection | Simple, zero deps, ~90% recall |
//!
//! More structures (HNSW, IVF) can be added as separate modules.
