// Stop / restore: Remove/disable; no teleport or inventory offer occurs.
// Notes: A landmark location is returned relative to this region origin, including cross-region offsets on compatible grids. Hypergrid behavior is grid-specific. Keep example captions and notecard lines short, preferably ASCII. Character clipping is not UTF-8 byte-budget clipping: multibyte text may reach hover-text or chat limits sooner and be truncated.
