— 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 rectangle object and horizontal sliders — entirely missing the required two-crown narrative, vertical slider, crown fall animation, water-level rise, splash effects, Heureka moment, and per-crown live readouts.
