— 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 ASCII art and live physics values, but completely misses the spec: no two crowns (pure gold vs. gilded), no vertical slider controlling crown submersion, no Heureka moment, dark background violates light-bg requirement, and the "slider" is a horizontal density/size control — not the requested crown-dipping vertical slider.
