-## Regression test for the Play -> Back navigation bug.
-##
-## The reported bug: after logging in and clicking Play, the user lands on
-## world_list.tscn; clicking Back returns to main_menu.tscn, but the menu
-## reset to a fully logged-out state (Play disabled, login form showing)
-## even though ApiClient still held a valid token. main_menu.gd's _ready()
-## used to unconditionally reset the UI on every scene load.
-##
-## This test drives the real navigation flow (change_scene_to_file) against
-## a live backend:
-##   1. Register a unique user so ApiClient holds a valid token.
-##   2. Load main_menu.tscn and assert it restores the authenticated state.
-##   3. Click Play -> world_list.tscn.
-##   4. Click Back -> main_menu.tscn.
-##   5. Assert the menu is STILL authenticated (Play enabled, welcome label
-##      visible, login/register buttons hidden).
-##
-## Run with:
-##     godot --headless --path . --script res://scripts/smoke_test_main_menu_back.gd
-##
-## Requires the backend to be running (default base URL
-## `application/agp/api_base_url` -> http://127.0.0.1:8000).
