// nisps/modes/memlcelium.hpp — MEMLCelium dual-voice synth + 2-track ratio
// sequencer mode binding.
//
// 4 abstract input channels → MLP[4, 10, 14, 18, 56] → MEMLCeliumEngine.
// The engine handles sequencer ticks internally inside process(); the mode
// surface adds set_playing()/update_bpm() helpers for platform glue.
