//! Phase 6D — encode-time CABAC stego scaffolding.
//!
//! This module ships the TYPE + TRAIT contracts that the rest of
//! Phase 6D builds on. Concrete implementations land in 6D.3+ and
//! the encoder integration happens alongside the first concrete hook
//! to avoid wiring call sites without test coverage.
//!
//! See `docs/design/h264-encoder-algorithms/stego-encode-time-architecture.md`
//! for the architectural decisions A1–A7 and overall design,
//! and `cabac-bypass-bin-stego.md` for the bin-by-bin invariant proofs.
