✓ 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 in most browsers (value 0 at bottom, 100 at top for vertical range inputs), so dragging down raises the crowns instead of lowering them; otherwise a well-rounded ASCII-art demo with correct physics, live values, splash/bubble effects, rising water levels, and a Heureka animation.
