+# ============================================================
+# 预加载 Terminal-Bench 2.1 数据集和 Docker 镜像
+#
+# 用途：
+#   terminal_bench_v2_1 运行时 Harbor 会按需拉取 Docker 镜像，
+#   导致首次运行很慢。本脚本先把数据集和 89 个镜像拉到本地，
+#   后续评测就只需要跑 agent，不用等镜像下载。
+#
+# 用法：
+#   bash bash/case/preload_terminal_bench_images.sh
+#
+# 注意：
+#   - 需要 Docker 环境
+#   - 89 个镜像大约需要几十 GB 磁盘空间
+#   - 执行时间取决于网速，可能需要 30 分钟 ~ 数小时
+# ============================================================
