Class PowerModelRGB

src/power_mgt.h:27–51

RGB LED power consumption model Used for standard 3-channel LEDs (WS2812, WS2812B, APA102, etc.) The model carries the brightness-to-power response exponent alongside the per-channel draw so the scaling behavior travels with the model and can be set in a single `set_power_model(...)` call.
