# NOTES
# ============================================================================
# 1. Always install system dependencies FIRST before pip packages
# 2. Use system python3-opencv instead of pip opencv-python (it's pre-built for ARM)
# 3. Create venv with --system-site-packages to access system opencv:
#    python3 -m venv venv --system-site-packages
# 4. For Bluetooth audio, make sure to pair devices first
# 5. For GPIO motor control, user must be in 'gpio' group:
#    sudo usermod -a -G gpio $USER
# 6. For Bluetooth, user must be in 'bluetooth' group:
#    sudo usermod -a -G bluetooth $USER
