Comprehensive and visually polished SVG implementation with correct physics (1000 g, 19.3 vs 13.0 g/cm³, 51.8 vs 76.9 cm³), live data panels, particle splashes, ripple effects, and heureka reveal — minor flaw is the heureka scale animation bugs out (transform reset inside the step loop) and water-level indicators show px instead of cm³.
