— 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 generic Archimedes buoyancy simulator with correct physics and live readouts, but is completely off-spec: no crowns, no vertical immersion slider, no Eureka moment, no splash effects, dark background instead of light, and the core narrative of two crowns (same mass, different density) is entirely absent.
