std::lerp includes NaN/infinity edge-case handling per C++20 spec which adds ~200 bytes of overhead per call. With 10 fields interpolated, this bloated the symbol to 2,038 bytes on BK72xx. Since all light color values are pre-clamped finite floats, a simple a + t * (b - a) is sufficient. Reduces LightColorValues::lerp from 2,038 B to 286 B on BK72xx. Also saves 16 bytes on ESP8266.
