✓ 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
Solid ASCII-art Archimedes demo with correct physics ratios and splash particles, but the slider direction is inverted (value=0 places crowns above, yet slider thumb at bottom visually corresponds to "in air" due to CSS rotate(-90deg) without flipping the logical mapping), and mass is static rather than a live updating value.
