+/// Audio format announcement carried in every Format packet. <see cref="Lane"/> was added
+/// 2026-05-11 alongside the BothIndependent audio mode — see <see cref="RenderRoute"/> for
+/// the semantics. The field is wire-backward-compatible: old receivers parse the first 32
+/// bytes of the format payload and ignore the extra; new receivers reading a 32-byte
+/// payload from an old sender default Lane to <see cref="RenderRoute.Mixed"/>.
