# help_ui_test —— §8.3 帮助窗 headless 自检（真 `helpwindow.py` uiscript + 假 client）。
#   godot --headless --path project --script help_ui_test.gd
# 校验：helpwindow.py 装载、19 条帮助行 + 任务栏标签逐字绑定（对齐
# `locale/locale/en/locale_interface.txt` 的 `HELP_*`）、close_button、open/close/toggle、
# 以及 SystemMenuUI.open_help() 懒建并打开本窗。缺 uiscript 资产时优雅跳过。
