AR Rung 2 — World Lock
Real AR. Content is anchored to the room, not to the screen.

What to do once you're in
- Sweep the phone slowly across the floor. A gold ring appears when it finds a real surface — that is ARCore locking on.
- Tap to drop an equipment card there.
- Now walk around it. It should stay put. That is the difference from Rung 1.
- Hold dead still for five seconds and watch jit in the top bar — that is tracking noise, in millimetres.
- Walk away, come back, and watch drift — how far the anchor has slid since you placed it.
Poor light and blank, featureless floors are what break tracking. If jit climbs above ~10 mm, that is the reason nine times out of ten.
