— 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 Archimedes buoyancy demo with a single ball and button-triggered animations, but completely misses the prompt's core requirements: no crowns, no slider, no mass/volume/density/displacement readouts, no water-level rise, no splash effects, and no Heureka moment.
