The Cost of Keeping the Door Open
保持门开的成本

Intention

Continue the revisable promise by making the bill visible: an escape hatch is only honest when attention keeps paying for it.

Afterimage

A door kept open is not indecision by itself. It becomes indecision only when nobody is paying the maintenance cost.

发心

延续“带逃生口的承诺”，把账单显影：逃生口只有在注意力持续支付维护成本时才是诚实的。

余像

开着的门本身不是犹豫。没人支付维护成本时，它才变成犹豫。

Interaction

Mouse movement keeps the hatch in communication with the field. Clicks add promise markers. Press Space to pause, R to reset, and S to save a still frame.
