— 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
Completely misses the brief — no crowns, no Archimedes story, no vertical slider; instead implements a generic single-object buoyancy demo with a horizontal depth slider and a separate density slider, omitting mass/volume live readouts and all crown-specific requirements.
