; T-1088: 3D locomotion sandbox — live-server-driven CharacterVisual walking the
; Gauntlet greybox. Scene tree per the T-1088 design §1.2. Launch:
;   T1: cd server && cargo run --bin settled-reach-server -- --test-mode
;   T2: SR_LIVE=1 ~/bin/godot4 --path client res://scenes/locomotion_sandbox.tscn
; Lights + environment follow the character_creation.tscn:65-92 recipe (the toon +
; inverted-hull outline shaders need lights and a WorldEnvironment in-scene).
