— 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 horizontal sliders and a single generic object — no crowns, no vertical crown-dipping slider, no Heureka animation, no two-crown comparison, fundamentally missing the core prompt requirements.
