When dragging the waveform seekbar, the player interface dynamically transitions to focus entirely on the timeline. The background album art dims to a dark gray, and the waveform scales up and centers vertically. The current timestamp enlarges and floats directly above the scrub point. As the user drags horizontally, the waveform scrubs smoothly with high responsiveness. Upon release, the interface seamlessly springs back to its original state, restoring the album art and standard player controls.
