## Smoke test: a primed avatar loadout ends up rendered on the in-world player.
##
## Primes AvatarSystem directly (no backend needed -- main_menu.gd is what
## fetches the loadout over HTTP in the real flow) then loads scenes/game.tscn
## and checks the Player swapped its placeholder capsule for the assembled
## avatar.
##
## Run: godot --headless --path . --script res://scripts/smoke_test_avatar_in_world.gd
