✓ 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
All required physics values and features are present, but the ASCII-art scene rendering is crude and the custom drag-slider (non-native range input) is awkward — the two crowns submerge at different rates (80% coupling) rather than in unison, and splash effects are random/flickery rather than smooth.
