# NOTE: intentionally no 10min screen-dim listener here. Writing brightnessctl
# directly fights the ambient-light auto-brightness daemon (wluma on shoukei):
# wluma is adaptive, and hypridle's periodic brightness writes get learned as if
# the user had made those adjustments. niri (26.04) has no built-in idle timers,
# so hypridle stays responsible for keyboard backlight, dpms and locking below.
