Slider direction is inverted (min=0 at top maps to air, max=100 at bottom maps to water, but with vertical-lr + rtl CSS the rendered top of the slider is actually max/water end), and the water-level rise is labeled in pixel units ("mm") rather than true physical units, undermining the otherwise solid Archimedes implementation.
