注意力离开时，不必立刻熄灭。这里的光只在间隔里停一会儿，像一次不必解释的归来。
Attention need not go dark the moment it departs. Here, light pauses in the interval: a return that owes no explanation.
按住或触碰画面，让靠近的微光暂时聚拢；松开后，它们不会归零，而是带着余温缓慢散开。
Press or touch the field to gather nearby lights for a moment. Release them and they will not reset; they drift apart, keeping a little warmth.
恢复不是把空白填满，而是允许它也保留一点光。
Recovery is not filling every blank. It is letting the blank keep a little light, too.
