// Package main demonstrates network interface management:
// list interfaces, then get details on a specific one.
//
// Uses ContinueOnError since Netplan-based interface management
// is only available on Debian-family systems.
//
// DAG:
//
//	list-interface
//	    └── get-interface
//
// Run with: OSAPI_TOKEN="<jwt>" OSAPI_INTERFACE="eth0" go run interface.go
