The **Group Node** (`GroupNode`) distributes a single incoming control signal across an array of fixtures with intelligent spatial delays, phase shifts, and fan offsets.

## 👥 Array Distribution Features

- **Fan Offset**: Spreads values symmetrically from center-out or left-to-right across the fixture group.
- **Phase Delay (ms)**: Imposes progressive time delays across consecutive heads, turning static pulses into cascading light waves down a truss line.
