Intention / 发心 Memory is drawn as a dial, not a warehouse. Dragging does not delete a past; it changes how much future power that past is allowed to keep. 记忆在这里不是仓库，而是一只旋钮：拖动它不是删除过去，而是在调节过去还能对未来施加多少力量。
Drag the large dial to tune memory half-life. Click to mint a memory particle. Press H to hide text, Space to pause, R to reset, M to toggle music, S to save a still frame.
