— 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 general Archimedes buoyancy simulator with correct physics and decent SVG visuals, but is entirely off-prompt: no two crowns, no crown-specific scenario, no vertical immersion slider, no falling/splash animation, no water-level rise, no mass/volume/displaced-water readouts, and uses a dark background instead of light.
