✓ 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 logic (t = 1 - rawVal/1000 combined with browser vertical slider rendering makes top=water), and the ASCII-art approach limits visual clarity of the rising water level, but physics values, live readouts, splash particles, and Heureka trigger are all correctly implemented.
