Nothing

A fullscreen idle timer that tracks how long a user spends not touching any input devices. The counter increments every second of inactivity and resets to zero on any mouse movement, click, or keypress. The longer you do nothing, the higher the number climbs.

The implementation was minimal TypeScript with direct event listeners for mousemove, click, keydown, and touchstart. No frameworks or build complexity — just a timer loop and input detection deployed on Vercel.
