✓ 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 (0%=air/top, 100% maps only 0–8 grid units which never reaches waterLevel=12, so crowns never actually enter water), physics transitions are binary snap (not submerging gradually), and the ASCII render re-randomizes water chars every frame causing visual noise.
