Two crowns Same mass, different density Vertical slider Slider works Slider controls crowns Slider direction correct Full slider range Fall animation Water displacement Rising water level Splash effects Physics correct Live mass value Live volume value Live density value Live displaced water Gilded displaces more Heureka animation No external deps Light bg / dark text Self-contained HTML

All prompt requirements are implemented correctly — same mass (1000 g), physically plausible densities (19.3 vs 13.0 g/cm³), visually larger alloy crown displaces more water, live stats update, splash particles and Heureka fade-in trigger at full submersion — but mass/volume/density values in the panels are static text rather than dynamically computed, and the slider is a custom SVG drag rather than a native `<input type="range">` (works well but is slightly fiddly).
