# Low-battery notifications (nomarchy.batteryNotify) — the bar colors the
# battery @warn/@bad at 25/10% (waybar.nix battery.states) but nothing
# *notified*; this watcher fires a toast at those same thresholds. Session-
# side and self-gating on a battery being present (the powerprofile-script
# pattern — no system→home coupling), so it's a silent no-op on desktops.
# swaync shows critical toasts until dismissed (timeout-critical = 0), so
# the 10% one can't slip by unseen. Logic lives in pkgs/nomarchy-battery-
# notify (overlay), where checks.battery-notify exercises it.
