### UDP Traffic Analysis & Debugging
To inspect and analyze the raw UDP packets being transmitted:
```pwsh
# Detailed payload analyzer - shows format, dimensions, pixel statistics
uv run .\scripts\udp_payload_analyzer.py
```
**Example Output:**
```

```
The analyzer automatically detects the format, shows pixel statistics per color channel, and provides a hex preview for debugging. Perfect for verifying data transmission and diagnosing issues.
```pwsh
# Simple packet receiver (no analysis, just basic info)
uv run .\scripts\udp_sniffer_raw.py
```
