— 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 ASCII buoyancy demo with two generic blocks (sink vs. float), but entirely omits the two-crown scenario, vertical slider, live physics values, water-level rise, splash effects, and Heureka animation — none of the prompt's core requirements are met.
