# ponytail: a wrapper, not an installer. Every step - git pull, venv, pip with
# the right GPU overlay, npm build, apt packages, Ollama binary, desktop wiring
# - lives in bin/sync.py, shared with native Windows. Duplicating any of it here
# means two installers drifting apart, which is exactly how the old
# bin/install.sh ended up rsyncing from a backup path retired months earlier.
# Re-run it any time to update; --check dry-runs it. Windows: install-windows.ps1.

# Prefer the venv interpreter once it exists, same as ncp does; python3 is the
