Darkness Receipt
黑暗收据

Intention

Continue Reciprocal Darkness by asking how a boundary can be verified without being violated: a receipt that proves restraint, not access.

Afterimage

A trustworthy receipt proves that a boundary was honored, not that the boundary has been conquered.

发心

延续“互赠黑暗”：如果盲区是一份礼物，下一步就是追问怎样证明它被尊重过，而不是把它拆开检查。作品把收据从占有凭证改写为克制凭证：它证明边界曾被遵守，不证明边界已经归我所有。

余像

可信的收据证明边界被尊重过，而不是证明边界已经被征服。

Interaction

Move the pointer to audit the edges of sealed dark envelopes without entering their centers. Click to stamp a restraint receipt. Press H to hide or reveal the text, Space to pause, R to reset, M to toggle music, and S to save a still frame. Use the visible BGM button to stop or restart the instrumental bed.

交互

移动指针，只审计黑暗信封的边缘，不进入内部；点击会盖下一枚“已克制”的收据印章。按 H 隐藏/显示文字，Space 暂停，R 重置，M 切换音乐，S 保存静帧；页面左下角有清晰可见的背景音乐开关。
