# Toggle npm/pnpm between corporate proxy and direct (home) network.
#
# Usage:
#   source scripts/switch-network.sh corp    # AT&T / corporate proxy
#   source scripts/switch-network.sh home    # Direct internet (home/VPN off)
#   source scripts/switch-network.sh status  # Show current config
#
# This modifies ~/.npmrc. Must be sourced (not executed) to affect current shell.
