"""Offline target keyboard configuration.

archinstall's set_keyboard_language boots the installed system in a

detect-keyboard-layout.sh copies into Hyprland's kb_layout — without booting

anything. The Xorg 00-keyboard.conf that localectl also writes is not

generated: nothing on an Omarchy system reads it.
