//! Message types for the Feetech bridge.
//!
//! Positions are published in the unit configured on the bridge
//! (`"units"` key in `copperconfig.ron`):
//!
//! - `"raw"` (default) — raw 16-bit register values (0–65535).
//! - `"deg"` — degrees relative to calibration center (0 = center).
//! - `"rad"` — radians relative to calibration center (0 = center).
//! - `"normalize"` — [-1, 1] over calibrated min..max (same scale for leader/follower).
