//! Trellis and hybrid quantization for optimal rate-distortion.
//!
//! This module consolidates all trellis/mozjpeg-style quantization code:
//!
//! - **`ac`**: AC coefficient trellis (Viterbi DP) - the core mozjpeg innovation
//! - **`dc`**: DC coefficient trellis optimization
//! - **`rate`**: Huffman rate estimation tables
//! - **`compat`**: mozjpeg-compatible [`TrellisConfig`] and [`TrellisSpeedMode`] types
//! - **`hybrid`**: Combined jpegli AQ + mozjpeg trellis ([`HybridConfig`], [`HybridQuantContext`])
//!
//! # Deletability
//!
//! This entire module can be removed (behind a feature flag) without affecting
//! the core jpegli encoder. When disabled, the encoder falls back to standard
//! zero-bias quantization.
