- Drop overrideredirect on the dismiss UI: on X11 it bypassed the WM and silently killed keyboard focus on the Entry, so the user could not type the dismiss code. -fullscreen + -topmost still cover the whole screen. - Add _max_sink_volume() / _restore_sink_volume(): unmute the default PulseAudio/PipeWire sink and raise it to 100% at alarm start, restore the original volume + mute state on dismiss. This is the biggest audio lever — pcspkr is hardware-fixed and was already maxed. - pcspkr: 3 back-to-back 1.5s beeps per cycle (was 1x 0.8s) at near-S16 max amplitude. - Fans script: control every NCT pwm[1-9] channel, persist per-channel pre-alarm state to /run/wake-alarm-fans.state so restore needs no args. - Tests: 100% branch coverage on python_pkg/wake_alarm/ (140 passed).

# Control ALL NCT pwm fan channels for the wake alarm.

# Usage:
|
|
# wake-alarm-fans.sh max — ramp every pwm[1-9] channel to 100%
|
|
# wake-alarm-fans.sh restore — restore the state captured by the last `max`
|

# Must be run as root (installed in /etc/sudoers.d/wake-alarm via install.sh).

# Safe: fans are designed to run at max speed indefinitely.
