///     Per-family libplctag defaults. Picked up at device-initialization time so each PLC
///     family gets the correct ConnectionSize, path semantics, and quirks applied without
///     the caller having to know the protocol-level differences.
/// </summary>
/// <remarks>
///     Mirrors the shape of the Modbus driver's per-family profiles (DL205, Siemens S7,
///     Mitsubishi MELSEC). ControlLogix is the baseline; each subsequent family is a delta.
///     Family-specific wire tests ship in PRs 9–12.
