# get.sh — One-line bootstrapper for Triton Manage Server.
#
# Downloads the installer to /opt/triton-manage-server (Linux) or
# ~/.local/share/triton-manage-server (macOS), installs Podman if needed,
# then hands off to install.sh.
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/primatekuntech/triton-install/main/get.sh | sudo bash
#
# Pass flags through to install.sh:
#   curl -fsSL https://raw.githubusercontent.com/primatekuntech/triton-install/main/get.sh \
#     | sudo bash -s -- --gateway-hostname manage.example.com --manage-host-ip 10.0.0.5
