Slider direction is inverted (label says "0=Luft, 100=Wasser" but vertical sliders in most browsers render with 0 at bottom and 100 at top, meaning dragging up increases depth — physically backward); physics values are accurate (Au 19.32 g/cm³, gilded 13.15 g/cm³, same 1000 g mass), ASCII rendering with rising water, splash effects, and Heureka overlay are all implemented, but the duplicate slider event listener and the browser-inconsistent vertical slider implementation are notable code defects.
