✓ 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
ASCII-art rendering is creative and physics values are correct (19.3 vs 13.0 g/cm³, same 1000g mass), but the slider direction is inverted (bt-lr inversion logic reverses intent), there is no smooth fall animation (crown teleports), and mass/volume/density live values are static rather than truly "live" (only displaced water updates).
