✓ 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
Impressively complete ASCII-art implementation with correct Archimedes physics (gold 19.3 g/cm³, gilded 8.4 g/cm³, same 1000 g mass), live info panel, splash particles, rising water bars, and a heureka overlay — but the ASCII crown rendering has a bug where water-fill logic uses a broken `inCrown` check (never excludes crown columns, just rows), and the slider direction maps 0=air/100=water which is correct, though the label "Tief▼" only appears at the bottom without a complementary "Luft▲" at top.
