✓ 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
Slider direction is inverted (value=0 maps to crowns in air, value=1000 to water, but HTML range slider at DOM top = min = air which is correct in value terms yet the physical thumb-top position maps to "LUFT" label correctly — however the slider is rotated -90deg making its high end visually at bottom/"WASSER", so dragging down increases value and submerges crowns, which is correct directionally, but mass/volume/density panels are static (not live), only displaced volume updates dynamically.
