- E/R/T hotkeys to switch Translate/Rotate/Scale modes
- Rotate: drag gizmo axis to rotate selection around that axis
- Scale: drag gizmo axis to scale selection on that axis
- Delete key to destroy selected actors
- Movement keys: arrows only + A (up) / Q (down)
- Removed ZQSD movement to free letter keys for hotkeys

- Click+drag on gizmo arrows to translate selected actors along axis
- Drag plane computation based on axis direction and camera orientation
- Axis-constrained movement with initial transform preservation
- Hover highlighting: gizmo arrows turn yellow on mouse-over
- Sphere sweep for easier gizmo clicking (generous hit radius)
- UE editor-style gizmo colors (dark red/green/blue)
- Fixed gizmo visibility toggle (component-level instead of actor-level)
