// Bridge between AAX MIDI nodes and pulp::midi::MidiBuffer.
//
// Extracted from aax_runtime.cpp's anonymous namespace so the thin SDK glue —
// the AAX_CMidiPacket <-> MidiPacketBytes copy on either side of the SDK-free
// reassembler/fragmenter in aax_midi_packets.hpp — is reachable by an SDK-gated
// unit test (test/test_aax_midi_node.cpp). The reassembly algorithm itself is
// already unit-tested SDK-free (test/test_aax_midi.cpp); this seam exists to
// prove the glue feeds it the right bytes/timestamps from real SDK node types.
// #239 AAX parity.
//
// AAX_IMIDINode is forward-declared so this header stays cheap to include; the
// .cpp and the SDK-gated test pull in the full <AAX_IMIDINode.h> / <AAX.h>. The
// definitions live in aax_midi_node.cpp and are only compiled when AAX support
// is enabled (built per-plugin and into the SDK-gated test).
