This is a browser-only demo of the character/overlay/audio system —
the same GIFs and countdown logic the native Windows app uses, minus
the actual keyboard/mouse lock (a browser tab can't do that; see the
native app for real input blocking).

Idle detection here uses mouse/keyboard events in this tab — it stops
working the moment you switch tabs or apps, unlike the native app's
real OS-level idle detection. Default timeout is 2 minutes so you can
actually see it trigger without waiting.
