# Stream random bytes from camera-qrng to the terminal.
# Start the server first: cargo run (or ./scripts/release-camera.sh if camera locked)
#
# Usage:
#   ./scripts/stream-random.sh [count]              # 10 lines (or 0 = infinite), no label
#   ./scripts/stream-random.sh [label] [count]       # label e.g. "Stream-1" so you can run in multiple terminals and see different streams
#
# Example (run in 3 different terminals to see 3 independent streams, never the same):
#   Terminal 1: ./scripts/stream-random.sh "Stream-1" 0
#   Terminal 2: ./scripts/stream-random.sh "Stream-2" 0
#   Terminal 3: ./scripts/stream-random.sh "Stream-3" 0
