* Lasso + Magic Wand panel controls — sliders, mode toggles, and the
|
|
* panel action buttons (Invert / Clear / Delete / Copy / To Mask /
|
|
* Bg Remove). The actual selection algorithms live in their tool
|
|
* modules (editor/tools/lasso.js, editor/tools/wand.js); this file
|
|
* just wires the side-panel UI to them.

|

* #ge-lasso-delete → lassoDeleteSelection
