//! Pacer configuration helper for OxPulse partner-edge.
//!
//! The per-subscriber `SubscriberPacer` is now provided by
//! [`oxpulse_sfu_kit`] (v0.11+). Partner-edge keeps this module
//! only to expose [`oxpulse_partner_edge_pacer_config`], which
//! seeds each new [`oxpulse_sfu_kit::SubscriberPacer`] with the
//! battle-tested production thresholds.
//!
//! # Threshold rationale
//!
//! | Field              | Partner-edge | Kit default | Why diverge                      |
//! |--------------------|-------------|-------------|----------------------------------|
//! | `audio_only_bps`   | 100_000     | 80_000      | conservative; validated in prod   |
//! | `medium_min_bps`   | 500_000     | 350_000     | avoids h-layer on weak 3G links  |
//! | `high_min_bps`     | 1_500_000   | 700_000     | requires solid 4G for f-layer    |
//! | others             | kit default | kit default | no observed deviation in prod    |
