//! Manifest entry for the latent-coordinate isometry gauge penalty.
//!
//! The implementation lives in [`IsometryPenalty`]. It is an extension-coordinate
//! penalty on the decoder pullback metric,
//! `½·μ·Σ_n ||J_n^T W_n J_n - g_ref,n||_F^2`, used to pin SAE latent chart
//! units before axis/rank selection penalties are interpreted.
