The overlaid, auto-hiding bar fought YouTube's seek bar for the same bottom
pixels: while ours showed it covered YT's seek + buttons, and reaching them
meant moving off the area and waiting for our bar to fade — a fiddly, "random"-
feeling dance keyed on mouse movement.
Now the bar is DOCKED and always visible: the video area is inset by the bar's
height (a wrapper around the mount, since YT.Player replaces the mount element
with its iframe and would drop a class set on it), so the bar sits in its own
strip and never overlaps the video. YouTube's seek/controls stay reachable by
hovering the video's bottom edge, just above ours. No auto-hide, no guessing,
no fight. Verified in Chrome: iframe.bottom == bar.top (no overlap), bar opacity 1.
