Slider direction is inverted (slider.value 0→1000 maps directly to immersion 0→1, but a vertical range input's visual "top" is value=max=1000, meaning full immersion at top — opposite of the stated convention of top=air), and the ASCII-only rendering limits visual fidelity of the crown fall and water-rise animations.
