# Installs Agent Village (Pixlage) on macOS or Linux:
#
#   curl -fsSL https://pixlage.app/install.sh | sh
#
# Files that curl downloads carry no quarantine mark, so macOS opens the app without the Gatekeeper prompt a
# browser download gets. Running it again updates to the latest release; your villagers and settings are kept.
