Your brain wants something for your hands to do.
Tap, scroll, swipe, repeat.
Just Fidgeting is that loop, minus the doom.
No feed. No likes. No notifications. Just squares. Each does something satisfying. Swipe cards, flip switches, adjust sliders.
It's fidgeting. Nothing else.
Eventually you notice. "Oh. I'm just moving my fingers."
Then you decide. Keep going, or put it down.
