Editor workflow:
- Removed auto-detection of BaseLevel (strip _Editor). Editor is standalone.
- User selects BaseLevel from ComboBox (populated from MasterCatalog.BaseLevels)
- "None" option for editing without a base level
- Selecting BaseLevel: clears current scenario, hides persistent level actors,
loads sublevel. Selecting "None" restores persistent level actors.
UI terminology: Scene → Scenario (save field, buttons, notifications)
GameInstanceSubsystem:
- Renamed PendingSceneName → PendingScenarioName
- Added LastEditedScenarioName/LastEditedBaseLevel (persist after Consume)
- SetPendingScenario() stores in both Pending and LastEdited
- ReturnToEditor() restores Pending from LastEdited, opens editor map
- EditorMapName auto-saved on first Play, used by ReturnToEditor
- OpenEditor() / ReturnToEditor() callable from gameplay BP
Play button: resets input mode before OpenLevel (fixes cursor in FirstPerson GM)
Test assets: FirstPerson template for testing Play/ReturnToEditor flow

Property Editing:
- New EditableComponent with two-step dropdown (Select Component → Add Property)
to declare which properties are exposed in the runtime editor
- Dynamic property panel below Transform: supports float, bool, string, FVector,
FRotator, FLinearColor with per-tick refresh and keyboard focus guard
- PropertyAction undo/redo via ExportText/ImportText reflection
- Custom properties serialized to JSON (TMap in ActorData, version 2)
- Copy/paste/duplicate propagate custom property values
Scene Outliner:
- Scrollable list of spawned actors in the right panel
- Click to select, selected actor highlighted in blue
- Auto-refreshes when actors are added/removed
Selection Filter:
- Only actors spawned by the editor (catalogue, duplicate, paste, load)
are selectable — static scene geometry is no longer clickable

Serialization:
- SceneData USTRUCT with Version, SceneName, Timestamp, Actors array
- ActorData: ClassPath, Location, Rotation, Scale per spawned actor
- SceneSerializer: SaveScene/LoadScene/ClearScene/GetSavedSceneNames
- Files stored in Saved/PS_Editor/Scenes/{name}.json
- Uses FJsonObjectConverter for clean USTRUCT-to-JSON conversion
SpawnManager:
- Tracks all spawned actors in SpawnedActors array
- SpawnActorDirect: spawn from class/transform (used by scene loading)
- DestroyAllSpawnedActors: clean scene clear
UI:
- Save field + button in toolbar area
- New Scene button to clear all spawned actors
- Saved scenes list with click-to-load
- Auto-refreshes scene list after save
- Clears selection on load/new

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
