Rotation gizmo:
- Quarter-arc rings via UProceduralMeshComponent (3D solid with depth)
- Dynamic arc facing: arcs flip to face camera based on octant
- Grey guide lines from center to arc endpoints
- Screen-space rotation direction (correct from any camera angle)
Scale gizmo:
- Arrow shafts + cube tips for per-axis scale
- Center cube (grey) for uniform XYZ scale
- Local space orientation (gizmo aligns with actor rotation)
Other:
- Runtime confirmation dialog (replaces FMessageDialog)
- ProceduralMeshComponent plugin dependency added

- PostProcessComponent on Pawn (unbound, applies to entire scene)
- Auto-loads M_PS_Editor_SelectionOutline material at BeginPlay
- Removed debug bounding box from Tick
- Custom depth stencil already toggled on selected actors
- Material needs to be created in UE editor (edge detection on CustomStencil)
- Instructions: use TexCoord + Constant2Vector offsets for 4-neighbor sampling

Spawn System:
- SpawnableComponent: marker component for Blueprint actors (name, category, thumbnail)
- SpawnCatalog DataAsset: lists all spawnable Blueprints with Factory for easy creation
- SpawnManager: loads catalog, spawns actors in front of camera, ensures Movable mobility
- Reads metadata from Blueprint component templates (no temp spawn needed)
Catalogue UI:
- Left panel with scrollable list grouped by category
- Thumbnail cards (80x80) with name below, click to spawn
- "Capture All Thumbnails" button on DataAsset: auto-generates from UE thumbnails
Undo/Redo improvements:
- SpawnAction: undo hides spawned actor, redo shows it
- Delete confirmation dialog (Yes/No) before soft-delete
- Undo/redo auto-deselects hidden actors and refreshes gizmo
- Proper cleanup of hidden actors when actions pruned from stack

- HUD with controls help, cursor auto-hide during camera ops
