✓ 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/top=air is correct conceptually, but CSS `transform: rotate(-90deg)` on a standard LTR range flips visual direction so slider handle up = submerged), and all ASCII art is rendered in a monospace grid with water animation, correct physics values, live data panel, splash particles, and a Heureka fade animation — but the ASCII medium limits visual clarity of differential water rise.
