Shipped. Verified against the repo 2026-09-05 during the roadmap audit.

SelectionMoveInterpolationMode lives in lib/constants.dart:307 with four modes (off, followPointer, followPointerWithSegmentGhost, gridStepEase), and kSelectionMoveInterpolationMode defaults to followPointerWithSegmentGhost - so smooth movement plus the snapped grey ghost is on by default. Consumed in canvas_painter.dart:978 and ported to the V2 line path as well.

Grid-snapped commit and single-undo-step transaction semantics were preserved throughout, so this did not cost anything on the history side.

Closing - it was already sitting in Done on the board but never closed.
