— 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 single generic sphere (not two crowns) with a horizontal volume slider and play/stop buttons instead of the required vertical slider controlling crown immersion depth; the core Archimedes crown comparison scenario is entirely absent.
