# install-macos.sh — Install screen-ruler and create an Automator shortcut on macOS.
#
# Usage:
#   ./install-macos.sh [-d INSTALL_DIR]
#
# The script expects a built binary at dist/screen-ruler (run pyinstaller first).
# It copies the binary to INSTALL_DIR (default: current directory), creates an
# Automator Quick Action that launches it, and prints instructions for binding
# a keyboard shortcut in System Settings.
