//! Module: sns::report::live::convert::params
//!
//! Responsibility: convert complete native SNS parameter responses into report DTOs.
//! Does not own: Governance queries, parameter validation, or text rendering.
//! Boundary: converts default-followee neuron ids to canonical lowercase hexadecimal text.
