//! Bounded exact Fock optics with explicit bosonic normalization and native Burn tensors.
//!
//! Fine modes are coherent; explicit internal-mode kets model distinguishability.
//! Passive interferometers
//! conserve total photon number; loss requires a basis containing every lower sector.
//! Component matrices use `[output_mode, input_mode]` creation-operator conventions.
