✓ 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
Solid physics and info panel implementation in a fully self-contained ASCII-art renderer, but the slider is horizontal (not vertical), the "animation" is a single-character crown in a text grid with random flicker rather than smooth graphics, and the Eureka trigger only fires at exactly slider=100 rather than at end of an animation sequence.
