// Click — point groups with {x, y} coordinates:
{ "errorId": 0, "solution": { "objects": [ [{ "x": 120, "y": 60 }] ] } }

// Slide — drag offset:
{ "errorId": 0, "solution": { "slide": [120, 45] } }

objects → array of point-groups; each point has {x, y} relative to the image.
slide → [x, y] drag distance/offset.
