— 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 vertical slider controlling immersion depth, dark background violates light-bg requirement, and the single generic object replaces the required two-crown (pure gold vs. gilded) comparison — the physics engine and ASCII rendering are technically solid but answer the wrong problem.
