# Description:
#   Level 2 wrapper module.
#
#   This file provides:
#   - Thin wrappers for Level 2 API functions (encode/decode) that delegate
#     to the corresponding core implementations.
#   - A demo function that runs end-to-end and computes SNR.
#   - A small CLI entrypoint for convenience.
