    "Support changes from the initial corner to the opposite corner without either passing below the floor.",
    "The tile stays rigid; its pale mark stays attached and its outline does not squash.",
    "The return tilt is visibly smaller rather than an endless equal-amplitude loop.",
    "The ending rests on the full original bottom edge, without another restart or floating gap."

  "steps": [
    "Confirm the starting contact is only at the lower-left corner and the other bottom corner has a visible floor gap. A flat starting tile would require an extra initiating push not supplied here.",
    "Request a small rock toward the other support, followed by a smaller return and a flat hold. Keep the motion in the original floor neighborhood rather than asking it to tumble away.",
    "Inspect each support exchange and the final base. Note whether the lifted corner descends to the floor before becoming the new pivot, and whether later tilt is smaller than the first."

Here one rigid tile repeatedly changes which existing bottom corner supports it, and the diminishing motion must end on the full flat base.",
