✓ 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
ASCII-art rendering is creative but crude, slider direction is inverted (value=0 at top means crowns in air but sliding down increases immersion, which is physically backwards for a top=air convention), and there is no genuine fall animation — crown state jumps discretely based on slider ratio with no time-based motion.
