core核心畫面

Something is sitting there ready but doing nothing — an alarm, a circuit, a chemical. One move flips it from ready to running. The word marks that flip: the thing already existed, you did not build it, you switched it on.

可以想成：某個東西已經裝好在那裡，但還沒動作——警報器、電路、一劑藥。一個動作把它從「待命」變成「運作中」。這個字標記的就是那一下切換：東西本來就存在，你沒有做出它，你只是讓它開始運作。
