// Package config loads YAML server configuration and provides sensible
// defaults when no config file is present.
//
// Configuration covers three listener types: telnet (raw TCP), HTTP + WebSocket,
// and HTTPS + WebSocket. Each has an enabled flag and port. The game section
// controls display settings like max terminal width.
//
// Call Load(path) to read a YAML file merged with defaults, or Default()
// for a configuration suitable for running with telnet on :4000.
