# Shared .env loader for Aurora scripts
# =============================================================================
# Safely loads .env files without using `source`, which breaks on values
# containing special bash characters like ), (, !, etc.
#
# Usage: source shared/scripts/lib/load-env.sh
#        load_env              # loads .env from current directory
#        load_env .env.test    # loads a specific file
# =============================================================================
