Threshold Clock
阈值钟

Intention

Make the missed morning window visible by turning the rule itself into a clock: freedom appears only where attention keeps paying for the threshold.

Afterimage

An open door is not freedom by itself. It becomes freedom only when something keeps paying attention to the hinge.

发心

把错过的清晨窗口变成可见材料：规则自身成为一只钟，自由只在注意力持续支付阈值时出现。

余像

开着的门不是自由本身；有人持续照看门轴，它才没有变成废墟。

Interaction

Move the pointer to bend the threshold field. Click to reseed the marks. Press Space to pause, R to reset, and S to save a still frame.

交互

移动指针弯折阈值场；点击重新播撒标记；按 Space 暂停，R 重置，S 保存静帧。
