The nav dock rides MUSIC_DOCK_HEIGHT higher while the music dock is up, but the
hide threshold was still measured from the bottom — so hovering the raised dock
read as past HIDE_THRESHOLD and it slid away under the cursor. Lift hideAt (and
the magnify gate) by MUSIC_DOCK_HEIGHT; the reveal trigger stays at the edge.
Also read musicDockPresent via a ref so the once-registered mousemove handler
reacts to music starting/stopping.
