2# uninstall-arje.sh — revierte lo que install-arje-as-init.sh hizo.
3#
4# - Borra /usr/sbin/arje-* y /usr/bin/{brahman-status,busctl,brainctl}.
5# - Borra el bloque ARJE-MENUENTRY de /etc/grub.d/40_custom.
6# - Regenera grub.cfg.
7# - NO toca /ente/seed.card.json (querés conservar customización).
8# - NO toca /sbin/init ni systemd.
