— 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 single-object buoyancy demo with a horizontal slider and no crowns, completely missing the two-crown Archimedes/Hiero story, vertical slider, crown fall animation, splash effects, rising water level, and density comparisons that the prompt requires.
