#   👻  GhostReach — one-line installer
#
#   This script downloads GhostReach and sets up the `ghostreach` command on your Mac.
#   It runs entirely locally, sends nothing on LinkedIn, and never signs you into anything.
#   Read it top-to-bottom before running if you like — it is intentionally short and plain.
