— 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
Implements a general Archimedes buoyancy simulator (with cube/sphere/ship shapes and correct F_A/F_G physics) but completely ignores the prompt's specific requirements: no crowns, no vertical immersion slider, no fall animation, no splash effects, no rising water level, no heureka moment, and dark background instead of light.
