# Script Name: flipclock-wrapper.sh
# Description: Launches the AlynxZhou flipclock as a KDE Plasma screensaver,
#              triggered by swayidle after a set period of inactivity.
# Features:    Skips launch if any media player (browser, VLC, etc.) is
#              actively playing audio/video, detected via MPRIS through
#              playerctl. Kills flipclock instantly on any keyboard or mouse
#              input by reading directly from /dev/input kernel events.
# Dependencies: flipclock (AlynxZhou, AUR)
#               playerctl
# ==============================================================================
# --- DEPENDENCY CHECK ---
