Crate huesmith_core 

Platform-agnostic core for Philips Hue–compatible Zigbee lights.

Everything here is free of MCU/HAL dependencies, so it builds and is unit-tested on any host (Linux, macOS):

• color — CIE 1931 XY ↔ RGB, mireds/Kelvin ↔ RGB, HSV, CCT channel mixing.
• light — the light::state::LightState ZCL state machine and the light::LightOutput trait a hardware backend implements.
• hue — Hue device types, identity presets, and Zigbee scene parsing.

The hardware/Zigbee-stack side lives in the companion huesmith crate, which implements light::LightOutput on the ESP32-C6/H2 via ESP-IDF.
