-# 启动实验室副本并注入 ViewPanel。
-# 用 LaunchServices（open -n）启动，这样进程有启动时间，REA 的运行时 UI 观测才认。
+# 手动重启编辑器（实验室版）：
+#   ./viewpanel/run.sh                       # 打开默认样例
+#   ./viewpanel/run.sh <某个.spine>          # 打开指定工程
+#
+# 做的事：①杀掉已在跑的实例（避免同时开好几个 Spine 窗口）
+#        ②源码比 class 新就自动 rebuild  ③启动编辑器（后台，日志 /tmp/spineview.log）
