Usage: omarchy bar <command> [args...]

  use <id>                             Use a bar option as the active bar
  reset                                Return to the built-in Omarchy bar
  defaults                             Restore the default bar and service widgets
  position <top|bottom|left|right>     Bar position
  transparent <true|false|toggle>      Bar transparency

  omarchy bar use local.neon-bar
  omarchy bar reset
  omarchy bar defaults
  omarchy bar position top
  omarchy bar transparent true
