//! Shared embedding layer for QQL.
//!
//! - [`Embedder`] — host-agnostic dense/sparse API (batch dense by default when overridden)
//! - [`resolve_embeddings`] — rewrite `QUERY` / `UPSERT` text into vectors on the AST
//! - [`sparse`] — local wire-compatible BM25 sparse vectors (no network)
//!
//! Used by `qql` (runtime HttpEmbedder), `qql-edge` (FastEmbedder), and `qql-wasm`
//! (fetch / JS adapters). No Qdrant I/O and no HTTP client live here.

/// Host-agnostic `Embedder` trait, joint embedding output, and error helpers.

/// AST rewriting: resolve `TEXT` inputs to vectors via the configured embedder.
pub mod resolve;
