svg-geometry-placement-transform-offset-note.md

• SVG geometry drag commit receives the live preview translation in visual/container coordinates. Before writing geometry attributes (x, y, path points, etc.) for elements that already have a CSS transform, map that offset through the inverse 2D linear part of the original transform; otherwise rotated/scaled/skewed SVG shapes preview correctly but jump on mouseup.
• The conversion intentionally uses only a/b/c/d and ignores translation, because it is transforming an offset vector, not an absolute point.
