# YOUR APPLICATION INSTALLATION
# =============================================================================
# 1. Setup runtimes and databases FIRST
# 2. Call get_lxc_ip if you need the container IP
# 3. Use fetch_and_deploy_gh_release to download the app (handles version tracking)
# 4. Configure the application
# 5. Create systemd service
# 6. Finalize with motd_ssh, customize, cleanup_lxc
