# Install icloud-headless-mcp from the rolling latest build in one line:
#
#   curl -fsSL https://raw.githubusercontent.com/sjdonado/icloud-headless-mcp/main/install.sh | sh
#
# Every merge to main republishes that release, so this always installs
# latest main, stamped with its commit in `icloud-mcp version`. There are
# no pinned versions: a pinning argument is refused rather than silently
# installing latest.
#
# POSIX sh, run as root on the always-on Linux host. Lays down the worked
# example from README (service account agent-icloud, /opt/agent-icloud,
# loopback-only browser stack). A different prefix or account means the
# manual install in README instead of this script.
