# ── modules/core/no-sleep.nix ─────────────────────────────────────────────────
# Prevents the machine from ever sleeping or suspending at the system level.
#
# This operates at two layers below GNOME:
# 1. systemd-logind — ignores all hardware power events (lid, suspend key, etc.)
# 2. systemd targets — masks sleep/suspend/hibernate targets so nothing can
# trigger them, not even `systemctl suspend` or D-Bus calls.
#
# This is intentional for a 24/7 server/node. The GNOME-layer power settings in
# sovran_systemsos-desktop.nix remain in place as a belt-and-suspenders complement
# for active user sessions.
