//! Facade over the concrete embedding backend for the current target.
//!
//! Backend selection priority:
//! 1. `--features embed-fastembed` forces the fastembed (ORT) backend.
//! 2. `--features embed-tract` forces the pure-Rust tract backend.
//! 3. Otherwise the target-cfg in `Cargo.toml` picks the default:
//!    - fastembed on `aarch64-apple-darwin`, `x86_64-pc-windows-msvc`,
//!      `x86_64-unknown-linux-gnu` (the only triples with ORT prebuilts).
//!    - tract on every other target (aarch64-linux, musl, all wasm,
//!      aarch64-windows, AND x86_64-apple-darwin — pyke dropped the Intel-mac
//!      ORT prebuilt, so the facade routes Intel macs to tract here).
//!
//! Downstream code imports ONLY from this crate. The backend selection is invisible.
//!
//! `embed-fastembed` and `embed-tract` are documented as mutually exclusive.
//! If both are set, fastembed wins (the re-export below picks it first); this
//! is a soft guarantee — prefer enabling exactly one.
