✓ 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
ASCII/text-art rendering avoids real animation; slider direction is inverted (value=0 is air, value=100 is water, but HTML range inputs render bottom-to-top making this functionally backwards for a vertical slider); crowns teleport rather than animate, and displacement is binary (in/out) rather than proportional to submersion depth.
