1//! Stub AMF encoder, compiled when the `amd` feature is **off**.
2//!
3//! Keeps `amf::AmfEncoder` a real type so the dispatcher in `encode/mod.rs`
4//! compiles unchanged, but construction always errors — auto-select then skips
5//! the AMD tier. Enable `--features amd` to compile the real
6//! hand-rolled AMF FFI encoder (`amf.rs`).
