— 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
Entirely reimagines the prompt as a generic Archimedes buoyancy simulator with three horizontal sliders (density, fluid density, volume) — no crowns, no vertical slider controlling submersion depth, no fall animation, no two-crown comparison, no Heureka moment, and dark background instead of light.
