Move a ring

Move slides the lit ring one step at a time. Ünflat never says X, Y, or Z: the rows read Move ↔ Side, Move ⤢ Front, and Move ↕ Up, each with − and + buttons. Move is the first action on the Nudge card:

The ring moves rigidly, keeping its exact shape and dragging the surface around it along, and lands back on the grid every press. Moving a middle ring sideways is how a straight tower gets a lean.

A press that would carry the ring past the edge of the world, or fold the surface, is refused whole. Nothing half-happens.
