Introduce a switchable UI stack so the original Slate widget stays available as a fallback while the new CodeDesign-inspired redesign and a future UMG Widget Blueprint implementation coexist. - PS_Editor_MainWidget_Legacy: pre-refactor Slate widget, restored from HEAD - PS_Editor_MainWidget: refactored floating-HUD Slate widget with style asset, 9-slice panels/buttons, rounded brushes, icon pack, Play/Pause/Stop icons, spec-aligned palette and radii, File dropdown, outliner per-item icons, command palette - PS_Editor_MainWidget_UMG: abstract base class exposing a Blueprint-callable API (SetTransformMode, SaveScenario, Simulate, Selection...) and delegates (OnToolChanged, OnSelectionChanged...) so a WBP deriving from it can drive the editor end-to-end - APS_Editor_HUD: UIMode enum + UMGWidgetClass soft ref, picks the right widget at BeginPlay; separate typed accessors for each flavor Adds UI style system (UPS_Editor_UIStyleAsset DataAsset + FPS_Editor_UIStyle helper) with runtime PNG loading for icons and 9-slice brushes from Content/UI/icons/ and Content/UI/unreal_9slice/.
