     desktop CSS, forcing it to fill the full panel height even when
     the viz-drawer is collapsed. The space between the collapsed
     drawer toggle and the layout bottom becomes dead whitespace.

     Fix: Let results-layout shrink to content height on mobile.

     On mobile, stop the animation and show a single static message
     that wraps within the viewport width. The second buildStrip()
     copy (for seamless looping) and extra messages are hidden so
