✓ 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

Live mass, volume, and density values are hardcoded static HTML (not updated dynamically), so those three "live value" features fail; displaced water and buoyancy do update, and the iterative water-rise physics and splash particles are a solid implementation highlight.
