— 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 technically solid single-object Archimedes buoyancy simulator with correct physics and live readouts, but entirely misses the prompt's core requirements: no two crowns, no crown-specific fall animation, no vertical immersion slider, no Heureka animation, and dark (not light) background.
