👉 The "obviously fluid" refers to a quality or state where something moves, changes, or transitions in a way that is smooth, effortless, and almost imperceptible to the observer. It suggests a lack of resistance or abruptness, making the process appear almost seamless or natural. For example, when describing a person's facial expression changing from surprise to joy, the transition might be so fluid that it seems almost instantaneous, highlighting the smoothness and naturalness of the emotional shift.
