class_name InspectorPanel
extends VBoxContainer
## Property and behavior editor for the selected object (docs/architecture/editor.md
## §7.2 `InspectorPanel`).
##
## Visual Property & Behavior Inspector (Creator Studio):
## - Position, yaw, scale, and delete operations.
## - Visual rule builder for ScriptBehavior rules:
##   Triggers: on_interact, on_touch, on_enter, on_timer
##   Actions: give_item (Buffalo Chips / items), rotate, move, play_sound, spawn_from_catalog
## - Pure UI: every property & behavior edit calls back into `EditorCore`
##   (`move_object`, `rotate_object`, `scale_object`, `set_object_behavior`, `delete_object`),
##   fully supporting undo and redo.
