— 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 solid general Archimedes buoyancy demo with correct physics, live values, and animated waves/bubbles, but completely misses the prompt's core requirements: no two crowns, no crown-specific mass/density setup, no vertical immersion slider, no fall animation, no splash effects, no Heureka moment, and uses a dark background.
