# Usage: ./generate_arrays.sh run

# SAFETY: This script only runs when executed directly with 'run' parameter
# It will NOT run when sourced (which happens during LibrePortal startup)

# Only run if executed directly (not sourced) AND run parameter is provided

# the script keeps its zero-dependency property but still matches the look of
