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

Slider direction is inverted (min=0 at top maps to air, but the vertical writing-mode bt-lr means dragging up increases value toward water, which is semantically backward from the label layout); all core physics, live values, heureka, and ASCII art features are present and correct.
