— 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 well-built generic Archimedes buoyancy simulator with correct spherical-cap physics and live value readouts, but is entirely off-prompt: no crowns, no Archimedes/Heureka narrative, no vertical immersion slider, no water-level rise, no splash effects, and uses a dark background — almost none of the specified features are present.
