# Horatio — build & deploy to Android device (BL-9000)
#
# Builds a release APK and installs it on the connected Android device.
# Supports wireless ADB (IP) or USB (auto-detect).
#
# Usage:
#   ./deploy.sh                  # Build + install (auto-detect USB device)
#   ./deploy.sh <phone_ip>       # Build + install via wireless ADB
#   ./deploy.sh --install-only   # Skip build, install existing APK
#   ./deploy.sh <ip> --install-only
