Module modulators 

Encoding-side gain controls and optional named modulator bags.

All types here live in this crate only (no external neuromodulator runtime dependency):

• EncodingGains — generic scales (rate / threshold / latency / sensitivity).
• NeuroModulators / NeuromodulatorGainCurves — encoding-local helpers with biologically familiar field names for evaluating gains. Map your own application state into EncodingGains (see examples/sibling_gains_adapter.rs for a pattern).

Structs

EncodingGains

Scales produced by neuromodulator gain curves for each encoder component.

GainCurve

Piecewise-linear map from a modulator level to a gain scale.

ModulatorGainCurves

NeuroModulators

Neuromodulator levels consumed by gain curves.

NeuromodulatorGainCurves

Per-neuromodulator gain curves composing into EncodingGains.
