// nisps/modes/slp_workshop.hpp — SLP-Workshop mode binding.
//
// The Synth Library Portland workshop instrument. It reuses the MEMLCelium
// engine and MLP shape verbatim (4 input channels → MLP[4,10,14,18,56] →
// MEMLCeliumEngine, sequencer ticked internally in process()), but exists as
// a distinct mode so the workshop firmware carries its own identity (preset
// dir, display name) and foregrounds the adaptive-learning gestures that now
// live in ModeBase for every mode:
//
//   - Jolt   — held gesture, continuously morphs a scatter of weights and
//              freezes them on release  (Base::jolt_press/jolt_release).
//   - OU explore — Ornstein-Uhlenbeck random walk on the output vector
//              (Base::set_explore_intensity).
//
// Both were ported from upstream memllib InterfaceRL (see ml/jolt.hpp,
// ml/ou_noise.hpp). Because they sit in the shared base, the synthesis
// mapping here is identical to MEMLCeliumMode — only the surfaced controls
// and identity differ.
