extends Node2D
## SandboxStage - Kid-friendly director sandbox stage (Phase 2).
##
## A self-contained visual stage for placing terrain, props and stickmen from a
## palette, with EDIT (build) and PLAY (simulate) modes. Selection uses geometric
## hit-testing; objects are dragged directly (no move handle) and rotated via a
## ring handle. A placement ghost previews the object under the cursor, and an
## optional snap-to-grid + grid overlay ease placement. NOT wired into the editor
## - run standalone via F6 on res://scenes/sandbox_stage.tscn.
